Even $700 seems expensive for a basic wall charger. I see them as low as £225 (USD $310) here in the UK[1], so expect them to get cheaper as the market develops. Of course, the real cost is in the installation and wiring.
For permanent installation in parking lots, they need to be weatherized, rugged enough to make at least a token resistance against people running them over, and so on.
The ones I was seeing were built into bollard-like posts.
Yes. Note that the one I linked to is weatherised (IP65), and claims "Corrosion resistant & fire retardant,
Impact resistant design" ... so it should be rugged enough to survive in typical apartment parking lots.
Obviously bollards will cost more, but something like this would be suitable if you have parking spaces up against an existing wall.
