I suggest to able to spawn your own vehicle(F2) at Race Track in Coliseum, the reason why I suggest this it is because the speed of the vehicles inside the marker is too slow and not so thrill for the other players to play inside the race track and we know other players like thrill and speed so the race will be more intense so thats why I suggest for that. but that doesn't mean that we will remove the marker, we only suggest to add a new feature.the vehicles inside the GUI can still be useful for those players who doesn't like speed vehicles.
