Reading this just highlights the fact of how barebones this game is :S Have any of the features mentioned above been implemented in past games? I swear some of them have. Which is doubly disappointing.
Ha I just finished a race on Suzuka in my career and also thought that bump was a bit much (just before the main straight). The only way to mitigate it is to accelerate towards the outside of the corner (on the left handside) while keeping the car as straight as possible until after the bump.
