The second point is beneficial to traditional car dealerships in the sense that, if Teslas were more affordable, more people would buy Model 3s over Leafs, Volts, or other cars. With the "cheapest" Tesla coming in at more than $70K, more than a few middle class families like my own are going to turn to cheaper alternatives sold by those traditional dealerships, be they hybrids or electrics.
The other big issue that I forgot to mention in my previous post is that Ford likes to claim that he is a champion of the middle class, and will fight for families, but two of his first major decisions hurt working or middle class families. At least in one case, it was done in favour of those car dealerships. Pretty disappointing, to be sure.
