The one who called it should not be the only one to acknowledge being ready before race can continue. Only tapping the screen should "override" ack from all drivers.If the YF can be resumed by controller from the one who called it (or by tapping the screen), why each players should ack the start?
Btw the time for the race to resume is 5 seconds (a long time when pulse is high and adrenalin is pumping). Could you make an option to select the time for race to resume after YF. (race resumes in x after YF)
