AlliedModders - prop_vehicle

When I give spawn the car can only drive alone to force the player into the car.

And if trying to get out is not possible.

I can exit of car using some line of NataliaAF code, but the problem is if KILL or REMOVE car entity, server crash.

I found several people with the same problem, is there any way to fix this?
