if you want to see real morons on the road, try LA - the land of the completely stupid!
people have accidents basically because they get distracted. (obviously this doesn't include a meteorite crashing down on you, but how often does that happen?) anyway, getting angry is a big distraction and that's why i try not to let the a$$holes get to me.
it seems to have worked. i've never had an accident.
(the things that these idiots do WHILE driving:
eat,
read (books and mags, etc)
yak in cel phones
put on makeup
think they own the freaking road and drive too fast for the situation, etc.
and maybe things i can't see - not even going there
)
