Two recent changes to supercharging lately, 1. Tesla started to charge for supercharging, and idle fees, and 2. Tesla is aggressively adding supercharging locations (here). One way to look at charging at home vs. outside, is like having a washer/dryer at home, or visiting a laundromat. I should be able to use a laundromat if I need to, but it is hugely convenient to have your own washer/dryer at home. A number of interesting parallel use cases emerge, Apartment dwellers: Some people who don't have space for a washer/dryer will always prefer to use the laundromat. Home owners who have just moved, or haven't figured out getting the charger installed: Some people whose washer breaks down may want to use the laundromat. Temporarily assigned somewhere for work: And others who are away from home, or moving, can use the laundromat until they figure out the laundry situation at home. 100D: Some will carry a large suitcase when travelling 110v: Or you can handwash Go to Nissan dealer and use chademo: Some will wear their underwears inside out. This begets the question, if a) 95% of my usage is covered by a 40KwH battery (100 mi range), and b) There are 100's of reasons for Tesla to keep the entry price point low (taxes, rebates), and c) Charging is ubiquitous, affordable and convenient d) People get comfortable with the idea of charging your car vs filling the tank, .... will Tesla bring back the 40KwH battery? I'm betting it'll happen!
