DCFC stations like that would certainly help EV adoption. Ultimately, however, I think it would make more sense to target resources at providing L2 AC charging at a large fraction of long term parking spots. Initially, the focus can be on doing this for new construction, including commercial and government buildings, multi-family dwellings, hotels/motels/inns, and curbside. Assuming that autonomous cars for hire become popular, this problem will get easier, since there will be more flexibility as to where to park and charge those cars.
Good points: I agree large numbers of L2 AC stalls would be better bang for the buck than DCFC. Coupled with autonomous driving, if your home or office doesn't have its own charging infrastructure, your car could hypothetically drop you off at your building and then drive to a parking garage with L2 plugs for overnight charging. Or as you say, just hire an autonomous car and never worry about where & when it charges itself.
But I also think we're further away from that vision right now vs DCFC. Tesla has already proven the viability of a DCFC network, but it's not yet legal (anywhere I know of) for a car to drive itself without a human ready to take over instantly. And even if all new apartments and offices are built with massive banks of L2 (which would be great!), there's still a significant barrier to adoption for many people, i.e. moving or changing jobs. Building widespread curbside charging (even L2) would require substantial commitment and investment from local governments; I wouldn't expect many (if any) localities to take such initiative any time soon. I'd love to be proven wrong though!
