EV fast charging connector battles and standards wars might be OK
It's a common lament that because there are so many EV charging plugs (including the 4 fast-charging systems -- Tesla, Chademo, US-CCS and Euro-CCS) that we need a universal standard, so that we can get the goal everybody wants of being able to charge any car anywhere.
That's a great goal, but standards slow down innovation. Tesla's proprietary connector is markedly superior to the two competing "standards" and there is yet more innovation to happen. What's better is to expect things to be different, and make it possible to build adapters, and stock them at the charging stations. Tesla has a Chademo to Tesla adapter, but even though there are perhaps only 200 places it would be useful to have it, they sell it to owners for $450 rather than just putting it in those 200 places.
Here's a rundown of the charging plug standards and the fight among them at:
