One of the reason I choose a Tesla was because of the superchargers that are everywhere in California, and because of their long range: I only need a 30min intermediate recharge to get from the Bay Area to Lake Tahoe. When I google for superchargers for other brands, I get very ambiguous results. There has been chatter about Tesla opening up its supercharges in the future (the selfish part of me would rather not see that happen, its I-80 charging lots before climbing to Tahoe are already pretty busy), but I've never seen another brand, so I guess it's not a thing yet. So what's the situation then? If you're a non-Tesla EV owner in the Bay Area, how do you make it to Lake Tahoe in a reasonable amount of time?
