Using Mobile Devices When Driving

The Americans are going nuts at the moment as new laws banning texting are brought in. Every time a state introduces a law, everyone behaves as though they just discovered a diamond in a dog turd.A tablet handheld device

Over here, the use of mobile devices when driving has been illegal for some time. You’d think it would be straightforward: don’t mess about with things that you have to hold in your hand, which could distract you when driving. But no, because you always get the ADI who thinks he’s a legal expert who can find loopholes within loopholes, and who cleverly defines a mobile phone as distinct from, say, a tablet or laptop.

As far as the letter of the law is concerned, the handheld mobile devices regulations refer to anything which is capable of interactive communications (two-way handheld radios are exempt) – and by that, it means talking, texting, emailing, web browsing, or navigating (where data has to be sent and received).

It would be difficult to argue that a tablet or laptop – by virtue of having to be held – was exempt if the police pulled you over for it.

The question often arises out in ADI Land because the DVSA is currently trialling the use of tablets instead of the DL25 paper marking sheet for examiners. Obviously, the examiner is going to be using the device while the car is moving during a driving test.

The reason this is not an issue is that on the driving test, the candidate is NOT being supervised. The examiner is NOT in charge of the vehicle. He or she is NOT taking the place of the ADI on a normal lesson.Hi-vis vest

However, if an ADI – one of the ones, no doubt, who already owns a hi-vis jacket and clipboard so he can pretend to be an examiner on mock tests – were to start using a tablet or laptop while the engine is on, then he or she is using a handheld device while being in charge of the vehicle. It’s “handheld” because you have to hold it!

Even if we go beyond the handheld devices law, if the responsible driver (supervisor or otherwise) is distracted by fiddling with anything in the car – cigarette, sandwiches, drinks, satnav, radio, window, fog lights, whatever – and it can be shown that this resulted in an accident, then there are other laws (driving without due care, etc.) which can come into play if the police are impressed enough by what they see.Sandwiches

Trying to play the amateur lawyer and telling the police that they’re wrong is pretty much guaranteed to impress them enough to throw the book at you. And quite rightly so.

An instructor should be in control at all times. If something is likely to impair that control, then whether it is technically illegal or not is not the issue. It’s just wrong – good old common sense tells you that.

But my iPad doesn’t have 2G/3G/4G connectivity! Someone actually came out with this on one of the forums. See what I mean about ADIs thinking they’re clever?

The law refers to two-way communication or data transmission – it doesn’t say anything about the mobile phone network. An iPad that doesn’t have 2G/3G/4G would be pretty useless if it didn’t have some way of connecting to the internet. Hence, it WILL have wi-fi connectivity, and so it WILL be classed as a handheld device if you’re stopped. Of course, this would be orgasmic for many ADIs, as they would be able to dream of going to court and proving everyone (especially the police) wrong!

And even if you managed by some quirk of fate to win your case on that technicality  there would be the small matter of driving without due care and attention. Yes, you might (just a tiny “might”) succeed in getting some judge to agree that the device you were holding in your hand and playing with was not included in the handheld devices regulations. But the simple fact you were doing it while you were supposed to be supervising your learner draws on older and much better established laws.

Is it really worth it? Just don’t use the bloody thing when you’re supervising a learner on normal lessons. You don’t need to… unless you’re a prat.

You Have To Laugh Sometimes

A story on the BBC Technology website tells of a new car headlight that can – and I quote – “shine ‘around’ rain”. True to the BBC’s objective of dumbing things down, there will now be a whole raft of people under the impression that light can go round corners!

Curved Light Now Possible say BBC

In actual fact, what this new headlight – which is in extremely early experimental stages – can do is pick up raindrops on a camera, calculate where they are likely to fall, then turn off light shining in that direction. It takes about 13 milliseconds to do this.

In tests, they managed to block out 79% of raindrops on a thunderstorm at 20mph, but only 20% of them at 60mph. They are dimmer than ordinary lights because they remove some of the radiation. One must assume that the more rain is in the air, the dimmer they are – which seems counterproductive to me.

On a more practical note, there is already a problem with those so-called adaptive headlights dazzling people and getting broken, and even BMW admits they are hard to keep working for the lifetime of a car. Given that most types contain sensors and motors to move them, the number of things that can go wrong (and the cost of repairing them) is much higher than with the traditional fixed type. Having a camera, beam splitter, and projector in there as well is obviously a huge step towards simplification. Not.

I also love the way that people gush about the road safety advantages of adaptive lights shining around corners, when the greatest safety benefits would be gained from having to go slower – not being able to do it faster! I mean, it’s Audis and BMWs that usually have these things, and those drivers really do not need any further encouragement or justification to drive like prats.

Being able to drive faster in the rain is just asking for trouble.

Project: Building A New PC

One of the most popular series of articles on this blog is the one where I detailed my DIY kneeling chair project. Other popular articles relate to some of the Computers & Tech posts – particularly ones which identify a problem or provide solutions. In fact, come to think about it the rest of the blog is most often found by people wanting answers to something.

I always build my own computers, and the one I’m using at the moment is a bit out of date. I built it back in 2009, and it was a fast machine then. However, I’m like every computer I have ever had, you start to notice that it isn’t as fast as the newer ones after a while. The old machine spec is as follows:

  • Windows 7 Ultimate 64-bit
  • Intel Core 2 Quad Q6600 CPU
  • Intel D975XBX2 motherboard
  • 4GB DDR2 RAM
  • nVidia GeForce 8800 GTS 320MB graphics card
  • 4 x Western Digital 500GB HDD
  • 2 x Optiarc DVD RW SATA drives
  • Sigmatel HD Audio 64-bit on motherboard

This is housed in a limited edition mirror-finish Japanese Steel Antec ATX case.

So, it’s time for a new one! And I’m going to detail the building of it on here.

First of all, there is nothing wrong with the case or the DVD units, so I am going to use those in my new one (as well as Windows 7). The spec for the new PC will be as follows (provisionally):

  • Intel Core i7 3770K CPU
  • ASUS P8Z77 motherboard
  • 16GB Corsair Vengeance DDR3 1600MHz RAM
  • nVidia Gigabyte GTX 570 Windforce 3X 1280MB graphics card
  • 1 x OCZ 256GB Vertex 4 SATA III SSD
  • 3 x Seagate or Samsung 1TB HDDs
  • Realtek 8-channel HD Audio on motherboard

I say “provisionally” because the motherboard might yet change, as may the graphics card and specific SSD unit. But the core spec will remain the same.

The new machine will boot from a solid-state disk (SSD) and use standard HDDs for storage.

I will keep this thread updated as I put the device together. To be honest, once you have all the parts the actual construction only takes an hour or so – installing the OS and all your software is the hard part!

SpeedView – Android App

It’s worth bumping this one to the top of the pile, as it seems that the new-model Fords have speedometers that aren’t completely visible from the passenger seat (the previous model wasn’t much better).

Note: As of April 2013, this app doesn’t work under Android  Jellybean.

Note: It appears that it was updated shortly after I wrote the above note, and it works under Jellybean as of October 2013.

The speedometer in my Focus isn’t always completely visible from the passenger seat when I’m on a lesson. The pupil’s hand might be in the way, for example, and this – combined with the cowling over the speedometer – can sometimes be a problem.

SpeedView

Instructors usually get a feel for the speed their car is doing, and can tell by the sound of the engine and just the general momentum whether a pupil is going too fast or not in relation to the speed limit. But sometimes you just need to be able to see what speed they are doing.

To be honest, when we come over the brow of a hill and there is a mobile speed camera sitting there, the last thing I want is to be leaning over saying “what’s the speed limit here?” and miss the damned thing. It hasn’t happened before, and I don’t want it to in future, either!

I’m sure certain pedants out there will be outraged at this admission, Stuff them! Any decent instructor will know that pupils DO go over the speed limit sometimes, and having a full-on Client-centred Discussion (with yoga thrown in) about it isn’t really appropriate right in front of a Gatso!

So, I found this brilliant little app for my HTC Sensation XE. It’s called SpeedView, and there is a free version as well as a pro edition.

It uses the phone’s GPS to give a real-time readout of your speed.

It has a compass, altimeter, accelerometer, and various stats and recording functions. You can export the records as GPX files if you want to.

It works in the car or on foot/on bike. And it is very accurate.

I tried a couple of other speedo apps that came up when I searched the Android Market, but they were absolute rubbish (the primary function of one of them was to crash when you tried to run it). But this one was way down the list – but it is easily the best one I have seen. I tried the free version (with ads on the main screen), but I liked it so much having trialled it all today that I have upgraded to the pro version (it only costs £1.50).

Highly recommended.

I don’t use it quite so much as I used to. When I first decided to upgrade my old Focus it was a little unnerving not being able to see the dials. But you get used to it – although some pupils make it worth switching SpeedView on from time to time.

Google Implements SSL

I noticed someone asking why Google’s homepage was suddenly “HTTPS” instead of “HTTP”. Before anyone blames the DSA for it, Google announced a while back what it was doing.

…today [Tuesday, 18 October 2011] we announced that SSL Search on https://www.google.com will become the default experience for signed in users on google.com. This change will be rolling out over the next few weeks.

If you log out of Google you get plain old http://www.google.com, but if you’re logged in you get the HTTPS version.

It’s a little annoying because it blocks search terms being passed to your analytical software. As several people have written in the comments to the announcement, Google can use data how it likes to drive business – but others can’t.

In fact, when you consider the reaction of the tech-savvy crowd, and Google’s possibly high-handed approach, a possible hidden reason for the original question starts to become apparent.

Augmented Driving App For Android

iOnRoad Android AppThis is interesting – an Android app which turns your smartphone into a device which tells you how far away from the car in front you are. It’s also supposed to be able to tell you when you deviate from lanes.

I’m going to have a play with it when I get the chance.

This article is a review, but the Android Market reviews differ somewhat, giving it higher and lower ratings. On average, though, higher.

What the app does is use your phone’s camera and GPS sensors to relate to road position and proximity to the vehicle in front. It can also take snapshots if you want it to. It has a range of other features which are covered in the article.

It’s called iOnRoad. Search for it in the Android Market.

Angry Birds Space

Angry Birds GameI’m sure most people with a smartphone have got Angry Birds on it. The game is very addictive and great fun – and totally harmless.

Apart from the original Angry Birds, there is Angry Birds Rio and Angry Birds Seasons – the latter two are updated regularly with new levels. But I saw in one of the tech journals that a new game – Angry Birds Space – had been released and had notched up over 10,000,000 downloads in just three days.

For anyone who doesn’t know, the game is about firing angry bird characters from a catapult at various structures, the aim being to knock out all the green pigs (who have stolen the angry birds’ eggs, hence the reason they’re angry). Well, in the Rio version it’s about knocking out monkeys, too, but the same idea. The backdrops are beautiful in all the versions, and in Seasons, as well as knocking out wooden structures, there are also snow and ice blocks.

Different angry birds do different amounts of damage. There are ones that explode, ones that puff up into big balls, ones that drop exploding eggs, ones which accelerate, ones which break into groups, ones which boomerang backwards, and so on.

Angry Birds SpaceWell, I downloaded Space, and it is brilliant. This time you are playing with gravity, and although you have angry birds with various functions as already described, their actions are affected by small planetoids, atmosphere, and the gravity-free environment away from the planetoids.

In addition, there are some new angry bird characters with new features.

Whoever programmed it is a genius.

It runs very smoothly on my HTC Sensation XE, but you don’t actually need a smartphone – you can play it on your PC. And it is completely free.

I’ve got three stars on all levels of the first three games (well, apart from the latest update to Rio, with two levels sitting at two stars). When I upgraded my phone I was worried I might have to start all over again, but there is a utility you can download which backs up your progress and then you can import that to your new phone when you’ve installed the games.

Space is going to be fun!

Agent Smartphone

SmartphoneThis is an interesting story. Aviva, the insurance group, is trialling software that runs on your smartphone and which records how carefully you’re driving.

I’m sure it won’t be everyone’s cup of tea. After all, having this software running is likely to slow down the phone, making texting that little bit more difficult.

Seriously, though, the kind of people who it’s aimed at – the ones who ought to be permanently tagged for the whole of their lives – are unlikely to take the option.

The idea is not that much different to the smartbox technology being used by other insurers – except that it is likely to be much cheaper to implement, and (unless they have very strict rules about its recording patterns) much easier to switch off or bypass for that crucial pratmobile meet at McDonalds on Sunday night.

Have people never heard of having two pay-as-you-go phones?

HTC Sensation XE

HTC Sensation XEI mentioned that I’d upgraded my phone to the HTC Sensation XE – I’d previously had the HTC Desire.

I was toying with the idea of the Sensation XL, which has a huge 4.7 inch screen, but I was put off by the fact that Orange didn’t have it on pay-monthly (and they said there were no plans to), and a few reviews I’d read didn’t rate it as highly as the XE. Also, it didn’t have a card slot, so you couldn’t increase storage.

Then, when I got to thinking about it (after having checked out a few promo videos), the XL is simply too big. The whole point of phones is that they’re discrete, but I reckon the XL wouldn’t fit in my shirt pocket. It’s bordering on being a tablet rather than a phone.

The Sensation XE has a 4.3 inch screen – massively larger than my old Desire, but still small enough to carry around. It has a dual core processor, and is infinitely faster than the Desire. Battery life is better, and Android 2.3 is definitely highly responsive. Even HTC’s Sense interface is smooth and trouble-free (and rumour has it it will upgrade to Ice Cream Sandwich – Android 4.0 – at some stage).

But the real reason I have written this article is that I just saw a TV ad for the latest Blackberry (the Bold). It made me laugh when I saw them using the “pinch” technique to manipulate the screen – which is only 2.8 inches!

It’s almost as big as my old Nokia 6600’s display.

Mazuma Mobile II

Another absolutely perfect transaction using Mazuma Mobile! I first used them when I upgraded my phone to the HTC Desire back in 2010.

I’ve just upgraded to the HTC Sensation XE, and upon checking I saw my old Desire was worth £73… here’s the timeline of events:

  • I “sold” it online Thursday 9th
  • I got the packaging on Friday 10th
  • I sent it off Friday early afternoon
  • Payment has gone into my bank this lunchtime (Monday 13th)!

Mazuma’s service is incredible – if you have an old mobile phone to sell following an upgrade they’ve got to be the No.1 Choice. The prices they offer are great – but the speed of the transaction is just unbeatable.
