I put my car seat behind the driver's seat. I take the seat in and out through the rear door, but when I go to remove it, I reach behind my seat and disconnect the seat first, setting it on top of the folded-down half of the bench seat, then retrieve it from the rear.

It's not the easiest arrangement in the world, but it still allows a passenger to get in and out of the passenger side door, and it's easier for the driver to disconnect the seat from the base if it's located behind the driver's seat. If I can figure out how to safely disconnect or remove the airbag however, I might relocate it to the front seat.
