What is a Euphemism for “Stupid”?

To add to the gridlock caused by road works – arranged by Nottingham’s incompetent council – an incompetent motorist decided to increase congestion today by “[becoming] wedged on the [tram] tracks” on Lenton Lane. You can’t beat a good euphemism. 

I have yet to find a version of the story which makes it clear that the retard who was driving had entered a tram-only area and had actually fallen into the track cut out. The phrase “became wedged” doesn’t tell the half of it.

Whoever it was should be banned for life. If you’re stupid enough to do something like this, God only knows what else you’d be capable of if you were allowed to carry on driving.
