I was riding on an Enduro bike when I accidentally submerged half of the vehicle in a small body of water. I understand that the engine is supposed to take damage when the wheels are in water (for whatever reason), but what happened next was definitely not supposed to happen.
I managed to climb the bike out of the water before the engine was completely destroyed and I was briefly able to continue riding as I made my way down a hill. The engine then broke down completely and I was left drifting downwards. Whilst drifting out uncontrollably I couldn't jump out which I thought was strange but maybe purposeful mechanic, but as soon as I crashed into a tree and the bike went to a total stop, I found myself still unable to get out of the vehicle, this left me completely stuck as the bike fell down to the floor.
Seemingly the only way I could get off the bike was to log out and back in, which I understand isn't the worst thing in the world, but the whole experience was certainly strange.

To reproduce this bug I would: destroy the engine by submerging part of the bike into water and then let the unoperational bike drift down a hill or slope. If you get my luck, the bike will still be running even when fallen on the ground, and you will not be able to get back up without logging out.
(make sure you don't go unconscious after the collision, as ragdolling off of the bike will free you)

I expected to be able to exit the bike when moving slowly down the hill - even if it may have led to me taking damage. I also expected to NOT drift forever on a bike spinning completely flat on the ground.
