For me I always think about the used market, because I have yet to buy a brand new car but I'm only 35. Used cars also represent the majority of vehicles on the road, I suspect with no evidence. Until the used combustion vehicles are gone, and really until truly cheap evs are available both new and used, we're going to have combustion engines on the road for many years to come. I'm expecting to get a PHEV for my next car so I can use the electric range around town but still be able to get on the interstate loops (we have an excellent wheel and spoke system here in my opinion and I happen to enjoy living near 410) or go north or whatever.
I see price as the main barrier to adoption. Power generation is definitely something that's going to be addressed, but if we're talking about 10 or 15 (or more) years, then there's time to build more plants. I think trying to conceptualize a model like "build a new plant every week for the next however long" doesn't take into account that we could build 50 plants simultaneously if the demand and money are there; it's not as though we have to build them in order. It's useful for showing the gulf we need to cross but it comes off a little "sky is falling" because that's not going to stop us from getting there. It's a delay at worst, and we need more and better power generation anyway. Looking at only one source, it appears that on average it only takes about 70-80 months to build a new nuclear power plant. I can't post links yet but it's from the iaea website, their latest press release about nuclear power for 2021.
I'm not very good at arguing so if you push back I'll fold like a cheap deck. I just wanted to say my piece.
