Spark plugs barely spawn now and only spawn badly damaged and if you barely over rev it it destroys the spark plug. Cars now also slide on inclines when the engine is off if wheels are damaged and when they stop they get stuck in trees. Stuck to the point that the tree won't let the car go. Cars were hard enough to get running and to drive last update now they are useless and a waste of time to try and get running. Make spark plugs repairable or spawn damaged condition or better only and revert wheels to where they always have the same traction.
