I've seen more and more players unfrozen without a car at the start of a race. Almost everyone runs past the first on the grid as far as they can and spawn a car in the middle of the road when the race starts. It can either give them an unfair advantage or mess up for others since he's blocking the road. It's a bad thing to do but also very understandable since it's so easily possible.
Can this bug be fixed?
What's can be done best if you see this happen?
A problem is the time limit. In about 3 second you, as admin, can't do much to prevent a car from being spawned in the middle of that road. Best chance is probably punishing the person with /cj before he spawns a car since kicking takes more time to type, but you don't have time to explain.
I suggest a temporary, short and easy command (like /ab ID) which would teleport the player to a position where he doesn't block others (maybe jail) and explain to him what he's done wrong and what he should do in such occasion (or to the whole server so it'll be done less). Maybe some info for bugfixing could be included (userinfo like ID and version).
I've banned agu who kept abusing (every race) and ingored what I did and said to him.
