So, the question I always have, is, can the grid even support this... surprisingly the answer is yes, but just barely:
"The record high level of finished motor gasoline consumption was about 392 million gallons per day in 2018."[1]
"Petroleum liquids–12.69 kWh/gallon"[2]
So, that's 12.96 * 392 Million kWh/day --> 5.08 Billion kWh/day
Smoothed out to the same rate every hour --> 211 Million kW
"At the end of 2021, the United States had 1,143,757 MW—or about 1.14 billion kW—of total utility-scale electricity generating capacity"[3]
So, in theory, we could run everything, and charge the cars when the demand was lower, at night.
