What's the state of designated parking spaces for such people? Just yesterday I crossed the parking lot at my local supermarket and passed a dozen extra-wide spaces right by the door, all marked with the generic symbol, painted in blue, and clearly marked for use by such patrons only. As it was most of them were empty, but that's good; every shopper with that need, currently at that store, had been able to park right by the door.
A short way beyond those spaces, are spaces marked for those shepherding children, which is less vital but still helpful.
So what's the state of this facility - extra wide designated spaces right by the door specifically intended for the people who need it - across the US and other countries? If it's being done, then this "smart summon" seems more of a gimmick. If it's not being done, it feels a little like an unnecessarily high-tech solution to a low-tech problem.
