Interesting idea. I have a near terminal case of doordentophobia, and if there aren't any HC spaces available (they are wider and have safety zones), I will park in the boondocks and use my cane. What the hey, I need the exercise. I have not yet had the intestinal fortitude to try the Summon function. It will be over in a couple of weeks anyway.
It's interesting, if I park in the less populated area, when I return there is often another Tesla or a new car or two parked next to me. Ahhhrgggh! A least these folks know about door discipline.
