Yes Patrick you're right. The 18 wheelers push you as the cab is about even with mine. The tankers don't give you the initial push but buffet you after they get around. The worst was about a 2 decker armored truck looking thing. It wasn't long but high and it screwed the air up until it was about 100 feet away.
