OK, going back to the quote, the secret weapon is separate to a weapon against the dealerships.
Weapon against the dealerships is where getting used car sales licenses, or getting into rental would allow easier access for customers.
Secret weapon for demand, I hope will be doing something about multi-unit dwellings, which is obviously an issue in some markets. Tesla has a patent for a L2 charging unit that can serve about 4 vehicles (I think), with the ability to apportion charge. Imagine a system that's:
- Multi-headed: 4 cables for each charger, install 1 for every group of parking spots you want to enable.
- Smart: allow settings for maximum total charge and apportionment.
- Uses local authentication: no Internet account management, just do it with swipe cards, NFC, RFID or something like that. Small number of users, Have something in the charger itself to allow an admin to enable a "key".
- Not-quite-metering: you only need 1 utility meter for parking if the charger itself can measure time of use and amount of electricity used by each "account". Cost(user) = Cost(all) x Usage(user)/Usage(all)
- Enable-a-cable: provide the unit at low cost and charge a fee to enable each cable.
The problem needs to be addressed, and Tesla wants to sell lots of cars, so why not work to help solve the problem and get Tesla branding everywhere?
