Well, you can’t read much into the way things are currently. Lots of EVs are sat unused. My car has 137 miles on the clock and under the normal run of things it would have closer to 1500.
Equally lots of businesses are not operating, using electricity on an industrial scale.
Hopefully though this virus will accelerate the whole WFH strategy for most office based firms, so car usage (and electricity usage) will drop. That would make V2G more viable too, as EVs would be sat idle at home rather than in an office car park.
