>In the US we don’t even test drivers over age 70 for competence

We don't test non-commercial drivers at any age after initial issuance of the license, which is apparent after a few minutes of observation while walking around.

That isn't true. If you move states they will test you again if you don't come from a state they like the testing for. This is just a written test though, there is nothing about do you apply the book knowledge to your real world driving.

Most people never make such a move, but it still happens. (this is an exception that proves the rule)

I moved states a few years ago CA to WY and was not required to take written test. computer in this state. The only thing they tested was my eye-sight.
