uh-huh! I had a similar experience to this
. I was coming down hill out at the far right of the long tunnel on Shore Side Vale driving a blue land stalker when I pulled and stopped left before the road to Donald's mansion.
Anyway a Criminal guy (he usually wears a jacket and green hat) walked in and got in to my car towards the driving seat (which is on the right) through me from the left side and in a bizarre glitch like situation swapped positions so now I was on the front passenger seat where he just came from and he was now driving the vehicle.
I called him criminal because he is the one that usually steals cars and drives of fast like drunk driving etc. Anyway since I noticed that he was driving and i was still in the car, I took notice and didn't want to end the game like before I planed to.
He drives around for 5 minutes Crashing, Hitting, driving almost vertically through the mt tunnel and each time doing damage to the vehicle until he crashes near the bridge opposite Toni's Shore Side house under a tree and catches fire. "blowing up both of us to the doom"
