In the early days of automatic transmissions reverse was the last position or at the bottom. It was changed due to a government regulation.

You want the drive gear to be as far away from the reverse and park gears as possible. On not-very-much-older automatics it was entirely possible to shift from drive to reverse or park while in forward motion, which annihilated the transmission and was very dangerous to the passengers. A lot of modern cars have a locking mechanism that engages to prevent this but that can fail of course. Having the order like this is not only safe, but it is consistent across vehicles, making driving a new vehicle east to pick up.

so, it starts from the order Reverse-Neutral-Drive, which makes sense, one-direction | no-direction |opposite-direction.
now we have to add park, well you could put it right next to drive, but it’s not a good idea as it could make it easy to accidentally shift to park while driving which isn’t a good thing, so the only other reasonable place is before reverse
also this makes it so after drive you can have L or S, which are just froward with a slight twist
