I don't think there are a lot of people that feel Summon isn't cool -- just perhaps a number of owners and prospective buyers that feel some other functions many more owners use every day, can use some long-delayed fixes and enhancement concurrently with the rest of Autopilot improvements (including Summon) being made -- not being effectively forgotten after an initial drop and press release of new functionality as has been the case much of the time in MS' short history with non-Autopilot capabilities.
I'm fortunate to not have a narrow space I have to fit my massive MS into my garage, but can see where Summon could benefit those that do. It certainly bailed me out a few months ago when I parked in a stall at Disneyland one morning to come back later in the day to a |>>%#~ that parked so close to my driver door it was impossible for me to open it. Instead of crawling into my drivers seat from the passenger side, I was able to back my MS out with my FOB, show off the wonders of my Tesla to a couple of friends I had brought along, get a bunch of oohs and aahhhs from them and on-lookers, and go on my way. THAT was very cool, but is the only time I personally have found benefit to Summon's capability in my use since it was introduced. As such, in my personal scheme of things that are important to me, I'll take fixes to acknowledged firmware bugs and bringing Infotainment up-to-par against the competition any day.
e.g I'd love to have my rated range be displayed like what Tesla promised before purchasing my MS 90D; not have phantom USB playing when I park most days which eats 2-3 miles of rated range per day between charges; less studdering of my Nav and music requiring reboots of the 17" while I'm driving; and of course adding several Nav/Infotainment improvements I've come to expect from previous luxury vehicles I've owned for 5+ years that Tesla does not prioritize as important in their scheme of things would be a huge plus and early Christmas present ...but that's just me.
My "good" Tesla MS could once again become "great", and perhaps IMHO become the best vehicle I've ever owned, if Elon and Tesla focused even a small team permanently resolving non-Autopilot bugs and then demonstrating constant improvement to these sort of non-Autopilot things for its owners today and tomorrow. Tesla's lack of attention to this brings the brand down in my concept of their focus and caring about today's owner VS Elon's vision for tomorrow being the only priority. IMHO Tesla no longer gets a pass on this because they are a new brand. Enough time has passed and scale been achieved, especially when we are talking about software functions that other mfgrs have had for years (so it can't be rocket science). With M3 reservation success, perhaps Elon doesn't care about the distinction of customer satisfaction from good to excellent, but if not, in my experience it will bite Tesla in the rear one day. Like most of us, I also want Tesla to be successful, and I'd be happy owing a Tesla to the day I die. ...but, Tesla must both deal with tomorrow (Autopilot), as well as today (firmware fixes and bringing Infotainment up-to-date to at least match the competition) to succeed and make me a totally satisfied customer that wants to once again recommend the brand without reservation as I did the day I brought my MS home, and then buy another Tesla one day. ...but again, that's just me. Peace.
