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.

I guess an open question (at least for me) is whether, in an urban setting, it's better to install a dozen fast chargers, or hundreds of slower chargers – like two for all 100 street lamps in an area.

What's more useful? Particularly in areas where people do drive a bit (the school run, shopping, whatever) but don't drive that much (they use transit, no huge daily commutes).

For me (apartment, shared garage, hard to adapt) I guess a more easily available but slower charger that replenishes the few kms that I drive every other day during a night seems more useful than scheduling a couple hours on fast charger on the supermarket… just to get there and find it's unavailable.

But they only installed 30 chargers, so it'll be hard to draw conclusions.
