I know that at my work, which is in a fairly modern office building meeting all the latest hotness in LEED and whatever, there are basically just a handful of spots with electric and there is so much demand for those spots that you're not allowed to park there for more than two hours at a time.

Parking has the double whammy of being entirely an expense, and possibly being outmoded. If you buy the electric autonomous fantasy of people no longer owning cars and relying on Uber-like shared fleets, that basically makes the vast majority of parking spaces obsolete, and so developers understandably are trying to make their parking lots easy to tear down and redevelop. (You can't really reuse the sloped floor plates of a parking garage for much else since all other building uses tend to need flat ground, and in any case the runoff from parked vehicles is quite nasty stuff.
