Congratulations, human: you are now an integral part of that door. More seriously, someone suggested pressing CTRL+0 to get out of such predicaments. If I'm remembering correctly, it resets something visual's position. Perhaps whoever posted this tip originally will correct me and better explain this undocumented trick?
Ctrl-0 pops you back into the last driving seat you sat in. If you spawned on foot and haven't sat in a driving seat yet, it'll do nothing. It also doesn't work with passenger seats.
