Okay listen sometimes people spawn on the road without a car it's really weird I personally cannot explain it. If this happens to you, just get out of the way and wait for the race to start. The instant it officially starts, hit
F7 and hit respawn. You'll be in the back with your car! This may seem like a real bummer, but it's actually a blessing in disguise because you're now safe from turn 1's terror.
ALSO if you start in the parking lot instead of the race track but still are definitely in the race do the same thing, it'll work probably.
