We don't have a usable national charging network. EVs still don't have the range of gas-powered cars. Many EVs are much more expensive than similar gas-powered cars. Few mechanics and dealers fully understand how to work on EVs. Conspiracy theories are rampant - somebody told me they thought the tires on EVs would give them cancer; another person told me he thought all EVs were just explosions waiting to happen (as though an IC engine is better!).
Chevy recently attempted to discontinue its small, affordable Chevy Bolt in favor of larger, bulkier, more expensive vehicles built on a new platform. It did this during a year where the Bolt sold record numbers and was widely hailed as one of the best and most economical EVs around. The Bolt converted people - myself included - who could not or would not have otherwise bought an EV, and Chevy tried to discontinue it (and later relented and said they'd offer a new version of it in the face of popular demand).
But sure, it's the consumer's fault. How dare people not buy new cars.
