I normally wont post this car. but, Since he was getting out of the throttle so much I think it will be OK. I believe this is the big one y'all were talking about.

You can see the back fire when he let off. Said the car was going into his lane at that point. I have no opinion on the matter just thought it might help with this discussion.
