..Tesla is using their Superchargers as a sales tool to sell to urban dwellers who they know damn well don’t have access to home or work charging.
That is the purpose of the Urban, lower current superchargers. I find those are usually empty by me (Northern California) while the higher speed, full superchargers are busy and some even have valets. Hopefully the Urban superchargers will expand to your area soon. I use them often when visiting clients in the Silicon Valley or Central Valley. In 20 minutes (or one latte at Starbucks) they add 100+ miles of range.
