AS OF AUGUST 2021 THE SERVERS ARE PERMANENTLY DISCONTINUED, ACHIEVEMENT NOW UNOBTAINABLE.
Servers maybe are back up? I have been testing the server off on since my last solution update and i found a random player in ranked my last test today, unranked and challenge series however, are not working.
Regardless EA as always still continues to be the worst gaming company ever. This game was once a very popular achievement game, but unfortunately was left in the dust.
Achievement description says it all. you need to win a race by crossing the finish line in reverse. this means ur rear end must cross the finish line. XD. the race must be ranked and it must also be a sprint race. it can be done on any track with any tier of car.
