long ago when I lived in pakistan a similar thing happened, it was when i was a young lad and all my idiot freinds were together having some fun times.
same khaandani morons parked like this completely trapping our car, a freind of mine opened up the tool roll in the car, used cable cutters to cut the handbrake cables off - reached under and used a small lever to dislodge the shifter cable (it was auto) and unselect parking gear - push the car right into middle of traffic. (all under 5 minutes)
we came back an hour later to find the family helplessly trying to work their car - (these idiots actually had offspring) - we just laughed and moved on. Epic fun time...
The peaceful way out of this situation, if I owned that toyota corolla would be to get in from the passenger door, lie the seats down, scooch my butt over to the driver side and drive it out. - but not many people are versed in that.
