When Ford and GM sold their soul and announced they were going NACS to sell more EV's and push their stock price up ( which didn't happen ), other manufacturers had no option but to follow. If you joined much later, it would be years before Elmo gave you access, back of the queue meant you will be left behind. Manufacturers panicked and one oafter another they caved in.
But, you should blame the other charger manufacturers - they are always broken and not fixed for months and each site usually has 4 chargers. If you go to any Tesla supercharger, 99% work and you have 10+ stalls. Tesla supercharger is the best for charging.
Combination of factors.
Now, they are all betrothen to Elmo.
So Europe and US have different charging. Great job by our auto industry...and Elmo blames the Gov for everything! His charger position explains how his thinking is irrational.
