Of course. There was novelty, a tech boom and governments doing everything they could to induce people to buy them. All of those things are diminished. California was ground zero, because of climate, the business and liberal policies.

I've always been a pessimist on the short term growth estimates of EVs, they didn't make sense to me. $35,000 cars (with subsidies) aren't really cheap cars. You can talk about how much maintenance EVs save, and yet the data says eg Teslas (the best of the best) have higher annual ownership costs than the competitors. You aren't really going to save money buying a Model 3 over a Honda Civic. That's a fact.

But, EVs aren't going anywhere, they'll only keep improving.
