going to have to disagree with you here. if you go to a big dirt race, i've seen as many as 44 modifieds on the track at once, and this was on a 3/8 mile track. no spotters, no mirrors, and they still weren't running all over each other. i imagine you can hear alot more in real life than in a game though, i figure that's got to be the only way they know where people are.
