Whole New Ballgame? Legacy car manufacturers may have one eye on road ahead and the other looking in the rear view mirror. It's like EV is a new toaster with lots of varieties out there. One list for 2020 that I saw had 108 startups. I think this site is more current but nonetheless, like the established car makers, BB can't ignore them IMHO. Some are developing their own mobile tech, or so they say. Should be much innovation coming as long as these companies can stay in business.
