So I have done a bit of testing, and it affects some cars more than others. all of the cars experience the "blip" but a few of the cars are far more responsive, and one of them is actually hard to stop sometimes due to how litte throttle it needs to maintain speed. and it means that when it goes over the track where the pitlane merges back to the track it sometimes goes of the track in the following corner because of the speed "blip" it gets. It really takes away alot of the fun at the moment, so hopefully there is a solution to the problem.
