You almost need an option which forces all drivers cars into 'ghost' mode for the first minute or two of a race because a 16 car grid is absolute carnage. I was rammed from every possible angle and the damage gauge was lit up like a Christmas tree at the start.
Would like everyone to take a lot more care to drive away cleanly, even if it means driving slower. The same could be said about braking for corners, far too many people following me seemed to brake much later than me, shunting me off the track. If you are behind someone you are obliged to avoid making contact and match their speed where possible.
