That's exactly my point/question. You're essentially saying 'the charge port's in the back because they put the electronics back there," but there's no reason they couldn't put the charging electronics at the front of the car rather than the back.
I agree that the design of the charge port and cable is well done it's just in a very inconvenient spot for what appears to be no good reason.
Driver-rear would be fine for our primary car. It would not be so good for our secondary car.
What would really suck both of our cars woudl be the Leaf's front-center.
We have a 2-door detached garage, Kona (front-driver) on the left, Volt (driver-front) on the right.
We are _not_ parked closed to the rear wall.
We pull in forwards and walk in and out of the garage through the main doors.
Kona plug is on the left wall, Volt plug hangs down in the middle of the garage.
But it's horses for courses. Driver-front would be best for us. But not for everybody.
It depends on where you park relative to the charger, where the charger is mounted, and so on.
Even passenger-side charging has utility. It's good for parallel roadside charging, or pull-by public chargers.
Generally sucks hard for off-street charging though.
Anyway, I don't see that backing up with a backup camera and parking sensors is a big hardship. I'm not good at it, but at least walls, curbs, painted lines and parked cars behave predictably.
