who actually caused the wreck? ok, here's is what happened and also explains why jr wasn't as ticked off as most thought he would be. when you turn any car, including race cars, it scrubs off some speed. maybe not much, but some. now in the real world we would simply give the car a little more gas to maintain or increase speed when cornering. remember, at talladega these guys run wide open all the way around the track. when jimmy made his move on jr it took a little speed off...very little, but just a tick. brian started to go with him at the first move. when jimmy made his move jr put a block on him, making jimmy have to turn the wheel a little more to get by. this second move scrubbed off a tiny bit more speed, and that was enough to let vickers make that 1/4 inch of contact and turn him into jr. just a restrictor plate event...no ones fault.
