The latest data shows US sales surge past the five percent "tipping point" for mass adoption, the same year the International Energy Agency found that global EV sales would hit a fifth of the total.
The rate of change is what's staggering. It took 10 years for the US to sell its first million battery electric vehicles, two years to sell its second, one more to sell its third and by the time the third quarter sales figures are added for 2023, under a year for the fourth million EVs sold, according to Bloomberg Green analysis.
This is without plug-ins or hybrids included. If you include those, then cars capable of running fully-electric at least some of the time have already hit a million sales inside a year in the states - just nine months, in fact.
California had been the first top 10 global car market to reach the five percent mark, where Tesla managed to knock Toyota off top spot in the state as the top-selling manufacturer.
Sales are now branching out, with states like oil-rich Texas, Florida, Washington and New Jersey leading the charge.
