Here is a short thought on renting a car in during the transition period.
Say you are a rental car fleet owner. Because of charging times, you likely are not going to expect people to return the rental cars "full" like they do with ICE vehicles.
So you have to charge the cars when they come back, it not only increases your turn around time between rentals, it leaves you vulnerable to "no charging" orders such as California issued over the weekend.
Do you:
1) Put people in a ICE vehicle
2) Do V2V charging from partial charges to get some to fully charged
3) Declare "force majeure" and decline their confirmed rental contract
5) Pay them to rent from someone else
6) Put in storage to handle 2 to N number of days of charging
7) Put in some form of local generation, in addition to any solar you can install in the lot
California's no charge edict for EV's should have every rental fleet (and other fleet owner) thinking this morning.
