A car with 2 full size seats side by side in the front as usual
plus a smaller seat behind the 2 front seats. This seat is pretty much like the usual 2+2 bench only that is narrower so it can only accommodate 1 passenger whose legs may be placed over the transmission tunnel partially between the front seats back rests.

Got this idea as usually its more comfortable (actually less uncomfortable) to sit in the middle of the rear seat in 2+2 cars.
