Even if all ICE production stopped today, we'd have existing cars on the roads for a while. As EV production ramps up, they should get cheaper due to economies of scale and the technology maturing. Currently the public charging infrastructure is awful, but that's also a chicken-egg problem that will solve itself. EVs already have significantly lower per-mile cost, so it's only the initial cost that's higher. I think we're not far off from the initial cost falling low enough that it won't make sense to buy new ICE, and then adoption will accelerate rapidly. Look at smartphones. There was a time when they were expensive toys and almost nobody had them, until they reached a tipping point.
