People shouldn't be allowed to drive when they are no longer competent.OK as long as you raise the age limit to 25 for start up drivers who are the major danger on the roads and lets look at the 30 - 50 age group who tail gate. Or even white van man who is under so much pressure to make a living he has to speed and take chances. And you want to pick on the the few old folk who cock up every year.
You can punish or re-educate drivers who choose to break the law or take risks - if anyone can be bothered to police them.
You can't make an old person competent when their faculties are impaired to such an intent that they are not fit to drive.
The comparison to be made is not with legal age drivers, but with young children, who we don't allow to drive for similar reasons.
