Unlike in testing, rather than being immediately teleported to the track you will get a painfully long loading screen before you appear at the track. Like testing, you will be floating in the air.
W a little tap and you'll fall onto the track, landing in your starting position. You may see some people moving, but unless the host is giving instructions for people to have a specific setup, try not to drive around just yet! There'll be plenty of time for that in the race.
After a bit, the countdown will start. Don't go yet! If you go now, you'll be declared a scumbag for jumping the start. Five red lights will appear on your screen, helping you to prepare for the start. After a random period of time, the lights will disappear and you'll hear a noise that sounds a lot like you should get driving!.. which, hopefully, is what you'll do. Good luck in the race!
