@ 3,000 meters -

Fall in a vehicle, vehicle will SOMETIMES disappear when it collides with the ground, sometimes it will not and show proper damage (sometimes a corner of the vehicle is partially in the ground which is a sweet effect showing it sinks in the ground... really it should pulverize the vehicle, but whatever).

You survive and so does everyone in your vehicle. You can eject once the vehicle as hit the ground.

This applies to all 4-wheel vehicles (including the quad) not to boats, you die in those.

Why you'd ever practically want to fall from thousands of feet in a boat or vehicle I don't know... but you can't die in the trucks anyways.
