Quitting the race, then choosing restart will sometimes leave me in a black screen right after it shows your driver cheering. Music still plays in the background, disconnected controller still pops if I disconnect it, nothing else works.
Stops people in races pushing another car to an unreasonable speed before starting the next lap. Or in the case of rivals cutting a final corner to take advantage of extra speed over the line.
If you dirty your lap in the last sector, just rewind past the point you went off track and run it clean. Your next lap should start clean then.
