To those who know about NASCAR and have seen this film...

I will add to that. It was exaggerated, it's a Hollywood movie. However, there is A TON of bumping and rubbing that goes on.

Depending on the track, on the longer, faster tracks, bumping is used as an advantage. It is called "bump draft". When two cars line up together they share wind resistance with the second car getting the biggest advantage. The second car is able to go faster because of less resistance (Tom Cruise demonstrates this on Nicole Kidman's leg). When this happens on the longer tracks, the second car will speed up and bump the car in front of him, giving that car a push or momentum and they both go faster. Most drivers agree this is a dangerous thing to do, but they do it anyway. The dangerous part is if you don't hit them straight on, you might spin the other car out. Dale Earnhardt was killed when another driver accidentally bumped the rear corner of his car, turning Earnhardt and sending him straight into a wall.

As far as "rubbin's racin'". It's true, it is. And it happens. Cars rub up next to each other all the time. Sometimes on accident, sometimes not. It's not as pronounced as in the movie, but it does happen a lot. When you watch races, you will see big, black circles on the side of cars. These are from the tires of other cars they rubbed up against.

When one driver tries to pass another on the outside, the car being passed might try and "squeeze" the passing car into the wall. Basically, the car being passed edges up to the wall and forces the passing car to either slow down, or make contact. So basically, they are pushing them into the wall. Again, that doesn't happen every time, but it isn't uncommon.

Hope this helps. And you should watch some NASCAR if you get a chance!

And by the way, I enjoyed the hell out of this movie. Being in England and not knowing the sport, what did you think?

So at one point in the race Cole is in last place. Then there is a big accident or of course he has to get through. But shouldn't there have been a caution flag raised? I mean he just goes right through and then suddenly catches up to every single car as if he is just speeding by them. Again I'm no expert but that can't be plausible.

Then when he enters the pit he screams to get out in front of that pace car or the race is over for us. Now they do get out in front of the car but I understand that he would have to basically go completely around the track catch up to all the cars and pass them again to regain his position which again is completely ridiculous.

Then in the last turn he and Russ Wheeler are smashing into each other. Wouldn't that give the cars behind them the ability to just pass them because they're obviously going faster? It's as if this movie completely forgets that there are other cars in the race.
