having seen first hand how quickly an old persons mental and physical state can diminish(from watching my grandparents), they should be retested at minimum every six months to have the right to drive.
Granted, most people that drive are idiots. I've almost been hit hundreds of times while driving or while riding by idiots, and that's the way it goes. But seriously, old people are notoriously bad drivers.
Also, it seems that the insurance companies standpoint of having higher premiums for males than females should be reinvestigated thoroughly, as (to sound like a terrible misogynist) i know i'm a better driver than most females of my age bracket are (which I would mostly attribute to cellular phone use, and as we are speaking in that instince of gender roles, a female is more likely to have a prolonged phone conversation whilst driving than a male, which I would mandate would equal the former belief that a male is more likely to be involved in an accident.)
regardless, those are arguments for a different day, and I'm glad at least someone got my point on the parade issue.
