Currently most rival events have a rolling start instead of the standing start at the start line like they did in previous games.
Personally I prefer a standing start, because I don’t know all of the cars and it gives me an idea how a car behaves while accelerating.
With the rolling start I have to slow down, drive to the start line and then start my lap/race.
I’d prefer an option to select between the two for each rival race I’m entering.
A bonus would be to disable the notification that a rolling start will be quicker, because after a couple of races I know that already.
