I completely agree with comments below that the premise of the article is silly: Tesla Motors isn't going to make cars that use petroleum.
This article makes the compelling case, however, that other auto manufacturers should rid themselves of the archaic franchise dealer network. The authors say that Tesla's direct-to-consumer approach is a corporate asset; another way to say that is that the franchise dealer networks are corporate liabilities of the 20th-century automakers.
Unfortunately, state laws protect these dealers at every turn, no doubt because the auto dealers are generous donors to political campaigns. Research done by Yale economists, though, shows that the friendlier a state's laws are to franchise dealer, the higher the price paid by consumers for their cars. Why is this no surprise?
