so when you stop for dinner you could plug in the Tesla to the generator to charge.... and yes I was thinking a smaller generator of the size to charge the car to full in 8 hours or so .... ( so I guess it wouldn't be all that SMALL that would take a bunch of watts ! )

Yeah, people have figured that out from side of road emergencies!









So they figured they’d just carry generator along.







Dragging generator around reduces efficiency greatly due to extra weight and aero-drag. Also converting to hybrid with running generator to charge battery while driving is not efficient either due to dragging around huge heavy battery. Better to get rid of battery and pump generator power directly to motors. Battery is major problem with EV, you lose 10% of power for round-trip. Don't get all power back that goes into battery. And miles-per-dollar spent in variable-costs will not complete with hybrids or even regular petrol engine depending upon your area's cost of electricity... more on this later...
