Re: Batteries in cars
...that's almost a week of going to work and back.
This whole thing hinges on the assumption worst case will be maybe one or two days without charge. Risky assumption to make.
What if circumstances contrive, as they often do, to mean no reliable charging for your car for over a week...? If you believe that's impossible, I suggest improving your imagination.
And for longer commutes, only a few days without charge would mean no commute. But not in a good work-from-home way. More of a your-unreliable-arse-is-fired way.
