The hose would stretch, but it could touch the body of the car and filling on the other side isn't as convenient because the hose gets bent near the handle. A similar number of cars with LHS/RHS filler caps would make for some nice load balancing at the pumps, but the problem is that most European and American manufacturers put it on the right side, regardless of vehicle model. Japanese cars sold in the US and Europe mostly have it on the left because the cars were originally designed for LHT and the engineers didn't bother to switch it. Many Nissans also have the dials of the dashboard in the center in order to cut some expenditure in producing LHT/RHT cars.
