... Plus let's not forget we aren't going down in terms of consumption, at least as long as the human race keeps advancing technologically. Cars hooked up to DC fast chargers already consume a LOT of power with new systems being developed consuming close to 1 MW (see: Desten, 900kW, or BYD's 1000kW) per charging vehicle. Now think of your average mid-size travel petrol station with 20 personal vehicle pumps and at least a dozen two pump stations for 18 wheelers / transports. Let's say the personal cars all take 1MW and the trucks (with higher capacity / charging) take a total of 4MW each. You'd probably average that out using on-site storage, but there is no way you'd be able to build the density (with current tech, or anything in the near term that I've seen) where you'd be able to store enough power to run all those "pumps" for a couple hours straight. Speaking as someone who worked for that industry while in college, you can easily see a few thousand vehicles a day at a mid-size in town station. Now not all of them will go fom "zero" to 100, but even going from 30 to 80 will add up fast.
So your college job as a gas station attendant gives you expert insight into electrical grid demand and EV charging?
You hypothesize 4MW for commercial vehicles, but never explain where that number comes from, nor do you account for the advantages electricity offers over petroleum products. Why are gas stations designed around the pumps currently? Because gas is toxic, dangerous, and difficult to control.
Electricity on the other hand is relatively easy to control and regulate--allowing delivery to individual parking stalls if desired. Amazon's Rivian delivery vans have 100 KWh batteries, so they can charge them using just 20KW for 5 hours, and have full battery early the next morning. Larger trucks will undoubtedly take more power, but the drivers are still required to take long breaks; so they will not be asking for a '1-hour charger' when a cheaper 8-hour charger will be less hassle and wear on the battery.
I think you also don't realize the best part of an EV is that most use cases NEVER require a visit to public commercial chargers. I haven't charged my EV at a 'gas station' for months--even though I use it heavily. Same goes for local delivery and service fleets--these can order batteries to cover their daily milage needs and charge overnight at their business.
The reality for many gas stations will not be inability to meet demand (as you imagine), but lack of demand as chargers get installed in businesses, retail parking areas, and dining locations.
