This is still not working, it used to smoke properly when there was not enough water in the radiator, was a very nice effect. Some other issues with cars as of 1.18, the car lights cannot be turned on when the engine is not running, I think this used to work but not 100% sure. They should turn on if there's a battery, and drain the battery energy (if the engine is not running). There's also a delay when you turn the key to start the engine, before the engine actually starts, which it did not used to have this delay.
