Yah, could be. I really don’t know what its like in California as we haven’t been back since before Covid.
6 bucks a gallon sounds steep though. Although honestly i have no idea how to convert kwh to mpg. Here it costs about 8 bucks (canadian) to go 500 kilometres, or at least here in the BC interior. But even at our place in california it was about 15 bucks to go about 500 kilometres (300 ish miles???). That was before covid so who knows. If we charge at superchargers its about three times that. (Which is why most try to charge at home). Youll have to get the calculator out to convert it to mpg. I have never been good at that.
I read an article about those who wouldn’t choose electric again. But from what i read the vast majority were apartment or condo dwellers with no way to charge at home. I get that. I recommend to people who don't have access to home or work charging to think it thru.
As for ling charging times. Hard to say. Depends on the car, the charger etc. Older models are slower. We rarely spend more than 15 minutes at a supercharger on road trips Unless its lunch of course. Not a bid deal for us. We used to spend more time than that getting gas at costco.

.
As far as power generation goes i couldn't say. Like much of Canada most of the power here is hydro. Depends where you live i suppose. Coal is a very small part of the power aggregate up here and will pretty much be gone within 8 years.
I’m not up on American politics so i’ll skip the rest.
Everybody has different needs and tastes. I would never go back to a slow clunky inconvenient stinky high maintenance gasser. But everybody has different tastes.
Cheers.
