Even with a charging station the extra space is minimal compared to the larger size of parking space you need to park an SUV rather than a normal car

Huge fraction of potential EV owners lack the ability to charge at home.

In the city I live EV ownership is at 37%. Very few charge at public charging spots daily. What happens is places that lack the ability gain the ability pretty quick.

Not bad! What city is that?

In Berkeley, California the share of EVs on the road is only about 5% today.

Norway has a fair number on the road - about 1 in 4 across the country. Quite plausible that some areas are even higher.

Bergen, Norway

if you drive 14,000 miles a year (US average -- twice that of EU average), you need to pull in 4,500 kWh a year.

At a 150kW charger that would be 30 hours of charging, or an average 5 minutes a day.

One charger would thus serve 200 cars in the US, 400 in the EU.

In the UK 2-in-3 cars have private parking space and thus potential for home charging. I expect the US to be a fair higher number as there's more space, but lets stay that figure.

That would make one charger serve 600 cars in the US, 1200 in the EU.

The largest chargers I've seen are half a parking space for two spaces.

Thus to serve 280 million cars you need to provide charging for 100 million, which at 600:1 car:charger ratio would be 160,000 chargers.

There are about 115,000 gas sations in the US. 2 chargers per gas station, using a total of 2.5 parking spaces, would be enough.

Thus moving to 100% EV would save massive amounts of space across the country.
