Because neither of those companies have a proprietary high-speed charging network in place, which is pretty much a requirement at this stage of the game. You can't just take an average EV and plug it into a Tesla supercharger. It doesn't work like that.
Furthermore, think about all the apartment complexes, condos, townhouses, and other shared housing in this country. Where are all those people going to charge their Honda and Toyota EV cars if even a fraction of them bought one today? On the one or two EV chargers per complex? I paid $3,600 to have a Tesla high-speed wall charger installed in my garage because I owned a single-family home and wanted the convenience of being able to charge my car within a few hours at my convenience. That wouldn't even be an option for the average Honda or Toyota EV owner in a shared housing complex.
So there's a lot more to the game than these manufacturers just cranking out mass-market EVs.
Keep an eye on these guys....
