The US consumes 376 million gallons of gas per day. Which is equivalent to a continuous power draw of 500 gigawatts.

Megawatt chargers? We'll need the generation capacity to support 500,000 of them.

What does whole country consumption have to do with building megawatt chargers?

The problem isn't trivial. If you have, say, 10 charging spots on a lot, each requiring a megawatt, how are you going to deliver that? Are you going to build a whole substation for every charging parking lot?
