Haven't tried reproducing this glitch and I don't know if it's useful, but...

Car turned over on driver's side door. When I exited the vehicle it clipped me under the pool. When I swam out of the pool bounds I fell into the void, then for some reason I was teleported to the middle of the street. Maybe it could be used for getting through walls in some cases?

Note: I used the Windows capture button which records the last 30 seconds, so I had to hit it twice and stitch the two videos together. Cut is around 0:07
