Consumer car batteries charge 20->80% in under a half hour these days, and are warranted for a minimum of 8 years. 30 minutes seems slow until you realize that you hardly ever need to charge the car away from home. I do not miss going to the gas station! I’d guess the mechanisms needed to swap the battery would be more maintenance than they are worth. I guess for delivery vans, which drive during peak solar production, doubling the number of batteries so you can charge during the day might make sense.

      Reading the question the answer was replying to, the conversation had already jumped the shark.

      Uhh, sorry I thought inductive roads were a dumb idea and I couldn't resist. But still I expected sarcasm to be obvious.

  "During snowstorm sometimes miles of the highway can be filled with stranded card. I wonder what will happen when all those cars are gasoline powered and the tanks depleted." You can literally camp in an EV for days with a comfy temp inside. And if you're stuck in traffic for _days_, you've got bigger issues or you live in an area where you should never drive anywhere without a Get Home Bag anyway. I live in Scandinavia where the temps get regularly below -20C and an EV is the best option to have by far. No car ever has been as warm as fast during winters.

    I am talking about charging / towing massive amount of cars. A bit o fuel for each can be delivered easily. Situaton is different with the batteries.

      Are you just inventing scenarios or is this something that actually happens somewhere in the world regularly? A massive amount of cars getting stuck in snow for so long they run out of fuel/electricity and need to be towed out one by one? It's not exactly rocket science to bring in a generator on site to charge the EVs enough to get them to the nearest charger. I could also invent a scenario out of my ass where the local gas station has run out of fuel because of a bank run style situation, but the electric grid still works just fine. How would gasoline powered cars work then?

        People in the US regularly get stuck in snow on a highway for over 24 hours? In non-trivial amounts, not just isolated cases of people being idiots during the winter and driving a narrow mountain road on summer tires and getting stuck? Those people really need a GHB and a propane cooker in their car at all times.

  Probably nothing. EVs can run the heater for at least as long as gas vehicles. A Tesla in camp mode can last days even at -25C.[1] 1. https://www.youtube.com/watch?v=VPudpniOmxY https://www.youtube.com/watch?v=VPudpniOmxY
