Yes, it won't happen all at once. And some use cases will survive longer.

I'm not sure size is the qualifier though. Electric busses are becoming more and more common. I think city vehicles make good candidates for EV - they don't typically go far from home. They are cheaper to build and buy, and much cheaper to run.

The reason I think EVs win is because of the "support system" ICE vehicles need. And as ICE share decreases that support system also starts to dwindle. So those services get more expensive. I'm thinking gas stations, mechanics, parts and so on. It becomes a death spiral.

It's not unlike the switch from mainframes to PCs. At the beginning there wasn't a contest, but now mainframe skills are hard to find and hence very expensive. So the market for them goes down. Indeed most mainframe suppliers (DEC, SUN et al) died off ages ago.
