You guys have no idea what you're talking about. The Tesla charging standard is significantly more efficient than the CCS standard others use. Not only that, but "Lord Suck" is currently making every effort to open Tesla superchargers to other [equally valid] EVs.

Manufacturers just don't want to.

Apple's Firwire was significantly faster than USB, but USB was way cheaper. So all the [frugal companies] invested in USB. CCS isn't much different.

Great technology constantly loses to cheaper technology.
