My idea of the passing aid is 2 vertical bars 1 on either side so as u pass another car say on the left the left bar fills up in proportion to how far u r alongside each other also maybe change colour depending on how close u r.
I think it would help especially off the line where most of the accidents happen and also when u get 2 racers having a close battle.
