Me and my friend found an Offroad Hatchback a bit above electro, as my friend entered the car he was unable to get out of it. The car was completely empty no doors, hood, weels, ect. The Hatchback was "parked" next to a metallic fence and the option to "get out" of the vehicle did not exist as a driver. However I also entered the car and sat in the passenger seat, my friend was then able to get in the backseat of the car and from there exit the vehicle. However I was now stuck instead. I tried to "get out" from passanger and driver seat but it did nothing, I was unable to get in the back of the car as it was not an option, but when my friend entered the vehicle once again as passanger I was able to get in back and get out from there. We solved the issue at last by relogging as we spawned outside the vehicle.
(We could also raise and lower our seats as we sat in them.)
