One of my cars has the tank on the driver's side and the other on the passenger. I didn't think I cared till reading this thread. Now I prefer the passenger side because I can open my car door all the way to get out at the pump and if refilling with a gas can on the side of the road I'm further from traffic. But ya, the convenience of easily getting out an not walking around the car is nice too and more useful.

I think I'm back to not caring.
