Thank you all guys for responding. Though this doesn't solve my problem, it actually makes me less pis*ed off... almost to the point where it becomes "on" :).

I was thinking of building a net with a lot of old CDs sewn onto it, that I'd put in my rear window and raise it when needed, so it would glare back :). But then, that may really cause some genuine road rage.

>Your method of letting them pass is a good responce. I always use the little day/night switch on my mirror. This tends to cut the amount of direct light I get from cars behind me. I assume they still put these in cars.

My Corolla was made in Canada, and it does have the lever to move the mirror while keeping its frame in place. The same one even the cheapest FIATs have always had.

>Here in Canada there are no laws that govern this. But if you get behind the police and they get anoyed. They'll let you know about it.

Well, at least I hope some of these guys run into some jumpy cops ;>.
