No, Tesla should have never gotten away with building a brand-exclusive charging station network in the first place.
Why?
I think the Tesla Supercharger network is the best and most influential thing to happen to the car industry for several decades. The Model S essentially turned out to be an "iPhone-moment" in therms of how disruptive it turned out to be. The automotive industry badly needed that huge kick in the back to get out of the endless cycle of selling the same thing year-after-year with as incremental little development as customers would allow them to get away with. Dieselgate also helped, as that busted the myth of "clean diesel".
At the time there was nothing planned by anyone, so Tesla essentially stepped out the path for whoever would come after them. Also, it's only brand exclusive because no others were willing to join them in the construction of the Supercharger network. Remember, this was at the time where the rest of the industry was busy being about as arrogant as Nokia was in 2007, and were mocking Tesla and labelling it as "pipe dreams".
As for legislation, I'm afraid we could have been stuck with the status quo in perpetuity. This would have opened the possibility for big oil sponsored legislators (who are numerous even here) to stifle progress and kill the solution to long range EV driving in its infancy.
Then they would be at the mercy of Tesla.
This is one of those times in which continent-wide legislation with strict guidelines about compatibility, interoperability, and standardized plugs is a good idea. WIth any luck it gets adopted worldwide. Worst case scenario, we end up with a lesser version of the current power plug nonsense.
Not if they went onboard from the beginning as a founding member, then they would have had equal control over the network. However, since they were dragging their feet, they would be at the mercy of Tesla.
I'm still positively surprised that the EU managed to be quick enough to mandate the CCS charing standard. Sadly, the Japanese and Chinese cars that are on sale here uses the ChaDeMo, which is limited to 50kw.
edit: stolen from reddit, what do we think of this? Sounds like good stuff to me, although I’m not sure of the effect on Norwegian electricity prices (ger dominated by taxes anyway and there’s nearly no dynamic tariffs anyway).
Our isolationists are loosing their shits over it, of course, they are rambling about it as if it was 1940 and the sky was full of Heinkel. But, I'm not worried about it. You have to see it in long therm, maybe, we'll get more expensive electricity for a shorter period of time every now and then, but on the flip side we greatly improve our power supply redundancy by adding more possible power sources to the mix, as Germany is getting more and more renewables online. This also means we can export a lot of our hydro power when we have a surplus, which is most of the time.
The opposite of cables like this is a very, very bad idea, as demonstrated by Texas this winter.
