it would be great if beamng had ignition(press button to start), engine cutout(when you let up the clutch too quickly,etc),flooding,and of course Backfire would be cool too(since there is fire simulation in game)
Ignition "simulation" and stalling are planned. Flooding is already in game. Backfire can't use the current fire system, what happens in a car to cause it to backfire is very different from what causes an actual fire.
