I actually have an Tesla and my fiancee has a disabled placard, so I would be able to use the aforementioned spaces.
Yeah, I suspected some such. I'm a little surprised they feel the need to provide exclusive access. That seems like an over zealous application of the law. I would think simply making all their chargers handicap accessible would be sufficient (and not handicap exclusive).
Making them all accessible is actually preferred by the people who advocated for the ADA; it's called "universal design". Blink should certainly have made all the chargers handicapped accessible, regardless of whether some of the spaces were marked handicapped-only. Their current implementation is not only an overly conservative reading of the ADA, it's a technicality-based reading rather than a "let's try to make things as good as possible for handicapped people" reading.
The need for parking spaces which are disabled-placard-only arises in a very specific circumstance: with access to buildings where there is high demand and the parking spaces frequently fill up, so that non-disabled people frequently have to walk long distances from the parking spot to the building. You don't want to make disabled people do the same thing.
If there aren't very many EVs, and you only have a few EV spots, it should often suffice to put the EV-only spaces near the front door next to the disabled-placard spaces, and to design the spaces with the extra wheelchair-unloading zone which disabled-placard spaces generally have. The small group of disabled people in EVs will happily use the EV spots regardless of whether they are marked with wheelchair symbols. On the rare occasion that the EV spots are full, they will move over to the nearby disabled spots and charge some other time.
Now, if the EV spots are filling up routinely, you need to build more EV spots. And if you build so many EV spots that many of them are a long long way away from the front door, why *then* you need to have handicapped-only EV spots. I don't think this is an issue anywhere yet, though I'm sure someone will pop up and prove me wrong by describing an installation of 100 charging spots.
Tesla should simply make all the supercharger stations handicapped accessible period -- "universal design". This means making sure someone who uses a wheelchair or cane can get in and out of the car while at a supercharger station. This isn't really very hard -- wide spacing between bays, arrange it so that the doors have clear space to open wide and aren't blocked when parked for charging.
(At the moment, the passenger side is more important, because I know the Model S can't really be used by someone in a wheelchair solo. But the Model X probably will be adapted for the disabled, so it's going to be valuable to make sure the driver can get out too. I've seen some people with no use of their legs, but massive upper body strength, swing their wheelchairs out from behind the driver's seat and transfer into them.)
Because the only service being provided by Tesla's Superchargers is, uh, charging, there is no particular need for Tesla to provide *exclusive* wheelchair access spots, because every spot is equally close to, uh, charging. However, if some of the spots are unusable for people in wheelchairs, *then* Tesla will have to start reserving some of the ones which are usable. Which is why they should all be usable, makes it much simpler.
This does show that Tesla should be careful about advertising. If Tesla starts advertising that you can go to a particular restaurant at a Supercharger site while Supercharging, then they might start getting ADA lawsuits if the Supercharger spots have been located way the hell away from the restaurant entrance. Probably nobody will bother them as long as the walking (wheelchair-rolling) paths between the Superchargers and the restaurant entrance are accessible, though.
