I finally had the logic of backing in to perpendicular parking spaces explained to me in a way that makes sense.

• The driver’s visibility ahead of the vehicle is better than behind it
• There are more potential hazards in the traffic lane than in the parking space

So nose-in-back-out puts the better visibility in the zone of lesser hazard, where back-in-nose-out applies the better visibility to the zone with the greater hazard.

@Cdespinosa Also,
* Teslas (with the exception of CyberTruck) don't have 4-wheel steering which means it's much easier to park in a tight spot in reverse. You can take a perpendicular slot on the right without needing to swing wide into the oncoming lane first.
* It's much easier to ensure you are straight and centered in the parking spot due to the camera and guide lines.
* It's much easier to tell if you are pulled into the slot at the appropriate depth due to the camera.
@bwhiteley @Cdespinosa all of the above. Whenever I back into a spot, I also consider it a little gift for my future self.
