Line 8: no need for return.
Line 13: Command handlers always get one argument. You need to parse it: playerID, vehID = arg:match('(%d+)%s+(%d+)')
Line 14: It should be tonumber(playerID) and tonumber(vehID)
Line 20: This function checks if the car is in sight (not behind a wall etc). You need to use doesVehicleExist to check if the car is streamed in.
