How often you need to load Tesla from 0% to 100%? Everyday? Current gas infrastructure would also be overwhelmed if everybody filled up from 0% everyday.

  Maybe someone uses less. Maybe two people live together and drive two cars, doubling the load. It's just an example, a way to illustrate how many panels might be needed or, conversely, how much energy is actually used by an electric car. It's still going to be far more panels than most people realize. 1887 hours of sunlight in my city per year. 100w per m2 of solar panel. = 189kWh per m2 per year. 100kWh tesla battery *365 / 189kWh = 193m2 of panels perpendicular to and tracking the sun perfectly. Getting that in reality means far more panels on far more land. Depending on slope, horizon and weather, you get to an acre (4000m2) very quickly. The math for something akin to a gas station, something that might want to "fill" 200+ teslas per day, becomes staggering. And big electric trucks? ... there isn't enough room in cities or even the suburbs. Widespread adoption of electric vehicles will need an extensive electrical grid.

    You're still saying people average 300 miles of their own car per day. That is 100k miles per year. The average is maybe 10% - 15% of that. Also, the S is a big car. Most people would be fine with a 3, or a Bolt, which have better economy.

    Isn't this a strawman argument though? I mean, I have an electric water heater (annoying, I know). It runs at 2500 Watts. That's 60 hWh a day!! A good €250 or so a month! Insanity! Except I don't run it all day.
