The fact that putting EV chargers in lampposts works in Europe doesn't necessitate that doing so will work in the natural environment, built environment and cultural context of the US. They have to do their own assessments to work out the best solution to the same problem in a different context.
Having some of the cheapest and most plentiful electricity in North America, courtesy giant hydroelectric facilities, helps. (Also why it's a major aluminum producer)
As an EV owner, crossing the border into Quebec from Ontario gives me about 5x the charging options. Everything from ski hills to grocery stores are set up with a mixture of charging types it's great. Get a 20 minute DC fast charge while running into the IGA to grab groceries and conveniences blew my mind.
There were a number of good EV charging ideas I saw on my road trip through Canada.
Electrify Canada was overall the best experience, though. No nonsense with installing a stupid custom app and setting up an account. Just tap credit card and go. Got full 150kW that my car can take. No hassle. Ate a burrito and returned to 80%.
This is partially because the car dealer lobby convinced congress to prevent the importation of cars less than 25 years old. Ironically, they did so using safety regulations, so a brand-new car meeting current European safety regulations is legally unsafe, but a 25-year-old car, complying with what European safety regulations were 25 years ago, less any deterioration in those safety systems, is legally safe.
