I was playing on a multiplayer server and got stuck in my car. How to reproduce:
Park car between wall and a sheet rope that leads to nowhere (floating wall)
Press E to try and get in car (character climbs rope instead)
Keep spamming E... That's all the steps.
I got inside the car eventually but was also stuck in the passenger seat. Couldn't switch seats or get back out.
Restarting the game client fixed it.

Bug #2
Taking a car battery out of a car while it's running and the car keeps running.
