So in response to "Tesla should join the existing standards" IE., j1772, no, sorry there is NOT in fact one standard outside of Tesla. For DC high power charging there are two in common use, CCS and Chademo, which with Tesla makes THREE different DC fast charge standards. And Tesla is the ONLY standard that integrated all forms of charging, slow, medium and fast, on a single connector.
Thus, the better standard does not have to adapt to the crappy standard (the betamax/VHS is another story). And Tesla fast charging (at 100kW and better) is already higher level than the vast majority of DC fast chargers at 50kW.
Should there be a single standard? Of course. But there is plenty of precedence that introducing standards on early, fast moving technology does not end well. Look at all of the iterations standard wall plugs went through, from light socket adapters, to blade plugs, to the modern three prong grounded (and in the USA it is still quite unsafe!).
And keep in mind that I make my living off J1772 chargers and I am saying this!
