I think that forcing people to take a driving test every year or so would actually help prevent a lot of these idiots from keeping their driving privileges, or at least make them realize it's a privilege NOT a right, and should be treated as such. I'd rather be 5 minutes late than dead!
I gave up on the speed thing a few years ago. It was just too tiring on long drives and snowy roads to get somewhere 30 minutes sooner.
It's funny you should mention recurring driving tests: my 88 year-old mother just had to do her written test again (all old people in Ontario do) Pain in the butt that it might be, she's a big fan of the requirement and thinks that she should have to do a driving test too. Says it refreshes her memory of all the little things you're supposed to know.
