I guess what confuses me is that most people with enough money to drive a Tesla keep it in a garage. I guess most offices probably don't have parking garages in suburbia, but I was surprised to hit control F "garage" on these comments and not see a single mention...

There are lots of upsides for future research and gained efficiency in the future though. Especially as electric moves toward big trucks down the road. (a semi full of solar panels could probably help propel the truck and save fuel etc.)
