FWIW with the Tesla charging stations, they've talked before about opening it up to other cars, and I can see that happening eventually. The problem right now is that, the existence of those proprietary charging locations is part of their competitive advantage. It sucks, and it would probably be better to live in a world where there were separate charging companies and car companies, but the investment in bothering to build out the charge network is coming from Tesla specifically because they want to get people to buy a fleet of cars, and that chicken-and-egg issue isn't sure to work out correctly if their investment were able to be quickly piggy-backed by other car manufacturers who waited until Tesla built out the high-capacity charging locations to bother putting out a car. When the Tesla charging network isn't so much of a competitive advantage, it will likely open up (per my earlier comment that they've actually mentioned this recently). None of this, of course, applies to laptop companies with their bullshit barrel chargers.
