Worth remembering that a large percentage of our population suffers from mental illness in some degree, undiagnosed and untreated. And, lots of them are behind the wheel. In my USA, which I will never see in my lifetime, the DMV would do psychological testing, difficult written and in car driving exams, every three years - no exceptions. Driving is a privilege, and 20-30% shouldn't make the cut.
