hey ... i know don wouldnt' have done that. but ... i've had homicidal thoughts myself at different times.
and even if the guy was racing his pregnant wife to the hospital (especially if he was doing so!) ... he should've been more careful.
the problem is that being in a car makes for bad drivers. when i drive a car, i have to keep telling myself to pay attention. i really do. you're in a comfy seat ... climate control ... the windshield starts to look like television. and what a boring show that is! ... so next thing you notice, you've gone 3-4 blocks and can't remember any of it.
then there are those people who are just plain jerks and try to run you down. i've had that happen in my neighborhood. not on highways. just plain jerks who honk and throw shit at you as they ride by real close. happens often enough.
