Admittedly I thought it was lower than that but Google's stupid AI kept telling me 10 hours. However even 30 minutes is a problem. I'm guessing that's the 15% to 80% charge time. That's still a SIXTH of the throughput of a standard gas station, so to achieve the same rate of refueling (and I dunno about you, but highway-side gas stations are always pretty busy) you would not only need six times the fueling spaces available as a gas station, but you would also need like... something for those six-times-as-many vehicles worth of people to do for half an hour. People already get impatient standing next to a fuel pump for the little bit of time that takes, you expect them to sit there for the average length of a television block? AND, that also assumes you can have the electrical backbone in place to let, what, 24 vehicles pull their maximum rapid-charge amount of electricity? Which is a fuck-shit-ass-load of electricity to pull.

Highway safety engineers are cheering - they want people to stop more often and take longer breaks for safety reasons. People can and often do stop only when the fuel tank is low, and they do all their bathroom time while the car is filling - this is very unsafe and people die from it. If the cars forced a longer stop those people would get some exercise, maybe take a nap - all things that increase safety. You are correct that the people will hate it.

Yes. Everything you said is true. The places I see level 3 chargers the most is Malls or shopping centers, where 30 minutes to grab lunch or do some shopping can be integrated with getting a charge. Battery tech is improving (some fancy stuff removing some components of li-ion batteries can improving the charging speed greatly: https://www.sciencedirect.com/science/article/pii/S1388248118302601 https://www.sciencedirect.com/science/article/pii/S138824811...) If charging time can be put down to a couple of minutes, the number of chargers go down... powering them is the last question... small scale (used fuel) nuclear reactors seem like a really promising option for fast power scaling. they can be built super fast (about 3 years - compared to the old-school options of 8-10 years). https://www.nuscalepower.com/-/media/nuscale/pdf/publications/nuscale-smr-technology-an-ideal-solution-for-coal-plant-replacement.pdf https://www.nuscalepower.com/-/media/nuscale/pdf/publication... Yep. It's a lot of work: money to do it all is up for grabs. Opportunity for a lot of people is knocking.

Lots of people will charge at home. I used a public charger yesterday for this first time in 6 months yesterday. It took 29 minutes. My time refuelling my diesel at 5 minutes a week would have been 2 hours. So for me it was a quarter of the usual time. Someone that can’t charge at home would be more.
