Musk suggested that the Model 3 would be "great for camping".
I'm a tad over 6 feet tall so I don't know how realistic it might be to make this work in a 3 with the rear seats folded back, but I'm hoping it is possible.
However, it's necessary to kind of trick the Model S via a series of settings to get it to keep the climate control going with the car parked. While this works, it's kind of a kludge from what I've seen in Bjorn's video. I'm hoping the firmware is updated to support an official camping mode that does everything in one press. Anyone know why they wouldn't make this an official feature?
