At least some folks are finding Smart Summon useful. https://electrek.co/2019/10/15/tesla-smart-summon-useful-for-wheelchair-users/
I think Summons is a great feature. I just think of all the times have gone to a restaurant, having to drop off my wife, park the car and then walk back in the rain. But it looks like Tesla still has a way to go before it is really usable. And their decision to have customers test and debug it for them is a little questionable.
