I recall looking at a car to buy, and the salesman toted the gas cap on the right as the "safe side".
The logic was, if you run out of gas, you can refill on the side away from traffic.
Dumbest design reasoning. Plan the side, for an event most people never experience?! Or if they do, once... and maybe on a rural dirt road, not necessarily a freeway.
Probably wanted an excuse for moving it.
Do you also hate airplane regulations for their dumbest reasoning? You know, when they try to avoid one in a million situation saving mere 200 people?
It's also nice not having to worry about opening your door and hitting the pump.
