The biggest issue is going to be other EVs with a charge port not in the standard Tesla location blocking multiple chargers for Tesla vehicles.

All Tesla vehicles have their charge port on the left rear corner, and because of this Tesla placed the chargers offset from the middle of the parking spaces and used shorter cables that would be able to reach this standard location.

Once things are open to other EVs if you have a car like a Rivian with it's charge port on the front left, they will have to park in one spot and use the charger designed for the parking spot next to them which will block spots that 2 Teslas would use in the past. For something like a F-150 with the charge port closer to the drivers door, they may have to park sideways and block multiple spots to make things work with the shorter cables.

Hopefully when they retrofit the chargers with the new magic adapters they also add longer cables to address this but we'll have to see how things eventually work out.
