shouldn't all gasoline filler tubes be on the driver side of the car?

i was driving my wife's new car and noticed it needed gas, so i pulled into a gas station, got out and couldn't find the little door that covers the gas cap. i found it on the passenger's side. then i had to pull out, turn around and pull back in facing another car at the pump. when he's done pumping, he has to back out because i'm blocking him.
i think everyone should refuse to buy any vehicle that puts the filler tube on the passenger's side. it's stupid and it causes "grid lock" at the gas station.

Yes, all fuel fillers should be on the drivers side! There is really no reason why this hasn't been standarized. It should be. I've run into the same situation before, and it can be a real pain when the station is busy. I think it's safer to put them on the left side.
