I object to being bullied by motorists

That's an interesting point; what is a given for good driving in terms of ability or psychological fitness?

Can we measure it?

If so, why don't we do this, given how dangerous it is to drive a 2 ton lump of metal about at high speed?

Ability, the standard legally tested caselaw is do they fall below/well below of the standard expected of a competent driver. "standard" being level to pass driving test. psychological fitness that's harder psychological profiling has it's fair share of holes so won't really work.
Advanced/high speed driving the goal posts changed the other year legal standard moved from normal driving test to an advanced one.
Making it harder to prove fault.
Currently any of theses test only apply once something happens and if chargers are made. Driving test is like any other exam pass on the day is no guarantee of future performance. Some form of continuous assessment and portfolio maybe as part of a bigger solution. Treating it more as a vocational skill than simple academic pass/fail exam.

On the one hand, you're right.
On the other, imagine writing that about pilots.

Imagine if it was as easy to become a pilot as it is to pass a driving test, and planes and helicopters were as cheap to buy and run as cars are.

Maybe a bit off topic, but reading admiral cloudberg's reports on air crashes shows that pilots are prey to all the same failings as drivers and cyclists. To make aircraft incredibly safe has taken lots of innovations including audible alerts, autopilots, cabin resource management and many others.

Interestingly punishments are not high on the list of safety measures, although frequent performance checks are.

Well worth googling!
