I still have some skepticism about cities prohibiting natural gas for heating, but that article makes some sense regarding the low power drag of heating systems vs. running an ICE.
Anything for >24 hours will have a problem, I suppose. The other point Lane made, about getting enough gasoline to a car to restart it vs. needing to tow an EV at this point is probably valid. I will imagine that at some point it'll make sense to have charging vehicles in service fleets to provide batteries juice when drained.
Not really. Computers will run for a long time. In fact, its marginally better to keep a computer running with a station keeping workload than to shut it down and start it up.
They have charging vehicles
They're usually ICE trucks with ICE generators in the pickup bed. The big issue with EV roadside charging is that it simply takes longer. If your ICE car runs out of gas, it takes 10 minutes to refill the tank. It takes a lot longer to charge an EV from a roadside assistance platform.
