That is a very sad story. :[

I got my license at 16 or 17 but I did not get to drive until I was 20 while my brother purchased his own car at 17 and drove whenever he wanted. I was still commuting by bike.
I think in drivers ed students are not getting enough practice - parents are supposed to let their kids practice with them but with gas prices I'm sure parents don't want to. My parents did not let me practice at home and the only time I got to practice was when I was with the driving instructor and that was a nightmare. We never had any talk about cyclists in class but I did tell the instructor they probably should. I remember when I was in the car with another student he drove on the bike lane a couple of times. :/

I feel like people these days don't know how to use their mirrors, how to scan the road and drive as if the road is just straight and all you have to look for is whether the light is green or red.

I believe I am an excellent driver and some times I can be too careful. My brother is also an excellent driver but he also has this need for speed which also pisses me off. He is too stubborn and won't listen to me. Well, I don't know what to do. It's like if you're in driver's ed you're well behaved in the class but when you get out on your own you do whatever you want because you're kind of not under authority. I don't know if that makes any sense. They should have some cyclist ride on the bike lane during the driving test lol.

I like the simulator idea. I don't know what an IQ test would do.
