Valid points. I think the G4 ECO with Lithium pack might fix the regen/ charge efficiency issue, to be on par with a plug in.

I do have solar cells, but EVs are charged at home over night, when PV arrays don't work. At any rate you have to live in a mansion to have enough north/south (as appropriate) aspect to meet your household needs and charge an EV.
