It take roughly 100 times longer to charge a car than to refill from a fuel pump so chargers need to be WAY more popular than gas stations. The “obvious way to handle this” is to build cities without cars at all, where people walk and bike and take the buses and trains.

I know this is an unpopular opinion, but I'd pick my own car over any form of public transportation any day. The privacy, convenience, utility is incomparable. You can build a city with all the buses and trains and cycles but I'll still drive my own car. I don't care about congestion. I don't care about cost.

> It take roughly 100 times longer to charge a car than to refill from a fuel pump so chargers need to be WAY more popular than gas stations. This is very misleading. It takes several minutes to fill a gas tank (depending on tank size, pump speed, and how many times the damn thing gets gaslocked). Charging a modern BEV does not take several hundred minutes. Fast charging exists and functions similarly for BEVs as it does for cell phones - fast charge for the middle bulk of the cycle, charge rate slows to a trickle above 80%. Chargers generally cost per minute, so you're incentivised to stay plugged in for the bulk fast-charge portion of your charge, not the trickle at the end.

  There are 2 DC fast chargers in the city of Berkeley, California. That's at best a total of about 400 miles per hour of charging, for a city of 120k people. EV boosters radically overestimate the widespread-ness of charging infrastructure. At a much more common 6.6kW charge station you're getting 25 miles per hour of charge. I can put about 350 miles of gas in my car in one minute.

    Ok, so your own numbers (350 vs. 25) come out as 14x slower, not 100x slower.

      No, that's 25 per HOUR vs 350 per MINUTE.

    If the lack of chargers was causing issues, it becomes a business opportunity. Electricity is everywhere already. It's really not an issue.

    Not really unrealistic? I have lived in an apartment. On weekdays off, I've had dealt with moving my car every few hours due to street parking time limitations. Having to move my car 30 minutes after plugging in to charge doesnt seem like a big ask.

      It chains you to your home and in case the charger is not in front of your home you have to walk too. If you have a tight schedule you often don't have that 30 min.

They already are way more popular. There are 168,000 gas stations in the US. How many electrical outlets are there?
