If you take a self-parking/-summoning ride to a dealership service department where they shuffle cars every few minutes, it's reasonable to leave keys or their equivalent. If the equivalent is a geofenced, limited duration, remote control credential generated only by an owner-initiated positive control process, then that's fine too.
Tesla summon is a laughable party trick owners try once and then never use again out of embarrassment, fear or frustration. After dealing with disconnect issues, it driving slower than a Turtle, or a surprisingly close call.
Another half baked feature they threw into the wild and never came back around to doing anything useful with for years.
I've owned a Tesla for three years and I often use the summon feature to fix a sub-optimal parking job, scoot the car forward so I can use the trunk, or drive the car out of a puddle that has accumulated during a rain storm. In that time it has never had "disconnect issues", nor has it gotten close to hitting anything. My only gripe is that it's kinda slow.
And if you don't like the feature you can just... not use it. It's not like the Tesla app bugs you if you don't summon.
You are using "summon" which is the feature to move forward/back a few feet. This is not a groundbreaking or unique feature to only Tesla, and I'm sure it works fine for your narrow use case.
The feature I was ranting about was called "smart summon" and was vaporware.
Remember the car was going to navigate driving across a crowded Target parking lot to pick you up from the front in the rain? Still in beta 4 years later. Apparently doesn't even work on vision cars?
People used to talk about Jobs and his reality distortion field, but legal would Apple legal clearly had more sway than Tesla's, as Musks abuse of the English language and state of reality is orders of magnitude more absurd.
Why should Tesla's (or anyone else's) convenience come at the cost of my privacy?
