A bit of a nitpick perhaps, but I'd say a personal parking area.

I don't charge in my garage, I charge in my driveway. My garage is stupidly small. My previous car, a small Subaru BRZ, barely fit in my garage. It doesn't help that there's a pillar right in the middle of it, preventing anyone from opening the passenger door of any car parked.

If I parked my Model 3 in my garage, I'd have about two feet between the front bumper and the back wall of the garage.

I agree "Garage" isn't the right phrase but what really matters is owning something to (or having autonomy to) attach a charger near where you park.

I guess "Garage" is just shorthand for owning a single family home.
