Implement sinking/floating cars on water

[madebr]

Cars do not sink in the water

How to reproduce:

• Start a new game
• Take the car with 8-ball, reverse and drive of the bridge
• The car will stay on top of the water and not sink

If the protagonist quits the car, he will respawn on the land. The car though will remain floating in the water without restarting the mission.

Cars should:

• float in water (not on top of water)
• protoganist must die

I'd say title should be more saying "implementing vehicles sinking", actually it sounds more like a bug.
