It just seems like the auto manufacturers could put the fuel door on the drivers side. Why should I have to walk all the way (you know it's a long walk)around to the passenger side to put fuel in my vehicle? None of my passengers ever put fuel in my vehicle.
Having said this, I do not have a vehicle where the fuel door is on the passenger side, however, it is funny watching people drive around the gas pumps fighting for a pump.
That's why you always keep a katana blade in your car to intimidate them!
The only logic I see behind passenger-mounted fuel fillers is in a coupe, where the doors are too long. So to prevent denting on the pumps they move the filler door to the other side of the car. The very first time I pulled into the gas station on my own was kinda funny. Just driving into thee gas station, calm and collective when... Oh crap, which side is the gas door on!?! Small panic attack. I heard an untrue rumour about the gas pump icon pointing the direction, but I saw the arrow, and got lucky. Whenever I can I try to use the same pump.
But if this is the place for random thoughts, consider this: My friend and I have come up with a way to replace your heart with two water pumps, power it internally, and have external charging ports and solar panels. Some of the ideas we come up with are borderline mad-science. This one really is!
