5 years ago major automakers didn't have full lineups of EVs already in production. Now they have, it's heavy industry, not tech, things take a while to R&D and ramp-up to full-scale production. Now there is full-scale production from multiple manufacturers, it only gets easier from here, maybe another 5 years is a good waiting time to see clear trends emerging.
