One of many things in aviation that remain a mistery to me is why Piper didn't put another door on PA28? Getting to the LH seat doesn't require as much effort (at least for me), but I wonder how would one evacuate aircraft in reasonable time if person on the RH seat cannot move due to, for ex. broken leg? Not to mention fuel selector, which seems almost deliberately located so that pilot could forget to switch the tank
Perhaps Cessna held a patent for two-door four-seat aircraft at the time
