alt Hacker NewsNo the filler placement is sort of a cultural or historical thing.
Usually European cars have filler on the passenger side while American and Japanese put them on the driver side.
Afaik passenger side fillers are more safe if you run out of gas and need to fill up from a canister at the side of the road.
While driver side fillers are more comfortable because you don't have to walk as far to get there.
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.
