I don't totally agree with the magnitude of how much more work needs to be done- we don't have one gas pump per ICE car, and electric cars don't need to be charged every day.

It's fair to say that people hogging chargers even when they're done charging is a problem, there's a public charger on my street that is near 100% utilization. However this seems pretty solvable- companies can just charge per minute as long as the spot is occupied and let the free market sort it out.

Adding public chargers is also a great way for places like malls, grocery stores, offices, etc to stay relevant, since my weekly shopping trips would probably be enough to keep a car topped off
