Do you think we'd have any non-Tesla nation-wide DCFC without Electrify America?
I agree that EA was launched purely by government action. So was Blink, EVgo, EVConnect, most of the Chargepoint network, and all of the hydrogen infrastructure. Even the first network of public Tesla chargers (70 amp Roadster chargers along CA-101) in California was directly funded by government money.
EA (and the rest of the aforementioned examples) barely works, is hardly used, can't be counted on, and probably requires unsustainable pricing to survive. I'm not, at all, convinced that EA will survive without something changing drastically.
Contrast with Tesla's Supercharger privately funded (with some government bonus) network and the difference is clear.
As far as the EV1: It was killed because GM (and the rest of the auto industry) had managed to convince themselves that EVs are a bad idea and the only reason they did anything was because of government mandates. The CA government flipped from BEVs to Hydrogen Fuel cells as Alan Lloyd retired as CARB chair, leaving to run the CAFCP (California Fuel Cell Partnership). The auto industry used this excuse to kill EVs since they realized that EVs truly were viable but would strand all of their ICE knowledge, IP, and investments.
This is probably the best example of how government meddling screwed things up and why we cannot count on the government for revolutionary breakthroughs such as electrification of transportation.
I won't say there is no value to the government, however, its ability to drive change is severely over-rated by many.
BTW: I had an EV1 for 3 years and 34,000 blissful, gas-free miles. I lived through that debacle.
As far as the Lincoln Highway: Ford and others, privately created the viable automobile. The government, ~60 years later, just created roads to drive them fast on.
You're welcome to believe in and promote government support of EVs and I'll wish you luck. I am likely, however, as I have been doing for the past 30 years, to come back and tell you I told you that it didn't help that much.
