Reproduction steps:
- Use any car / bike.
- Drive it at high speed.
- Hit alt + f4.
Actual result:
The car stops immediately while you’re being asked if you’re sure you want to quit the game, so you can abuse it by driving 300 km/h in city, and instantly stop if you are about to hit something / etc.
Expected result:
The car looses speed slowly, continues to go by inertia.
