Sorting out the menaces in a test? I doubt if you could do it one hundred percent. But in England anyway the driving tests just checks on knowledge about the rules of the road, and ability to carry out a road test. You could be a homicidal maniac and pass, if you had the skills and the knowledge.

I think it should be possible to devise ways of determining things like a tendency to road rage, and some level of common sense. If the upshot was that a fair number of people couldn't get driving licences, that seems fair enough to me.

After all, not everyone gets to drive. There are a fair number of people who can't pass the present test, because they haven't got the ability to control a car safely, so they'd be a danger to themselves and others. People who can control their cars well enough, but who can't control themselves, would merely be in the same situation, for the same reason.

And if they got offended at that, well it's true enough, as has been said, you can't avoid offending people all the time.
