The ability to use the phone or remote to move the car forward or back in a straight line is super useful and a cool, novel feature by itself. It’s also a buggy piece of shit that a few engineers could probably greatly improve in a month. Doesn’t seem like Tesla cares, it’s been stagnant for years.
Meanwhile Tesla is still charging people $10,000 for an FSD function that doesn’t exist.
Is it? It’s hard to think of a situation where moving a car I’m at most a couple of hundred feet from backward or forwards in a straight line by fiddling with my phone is superior to just getting into the car and moving it myself. Maybe I’m not finding myself and my car on opposite sides of a gorge often enough?
Someone parked too close to your driver's door? Just back the car out remotely and get in.
Parallel parked, then walked away from your car and noticed you didn't leave the car behind enough space to exit without scraping your bumper? Pull it forward a little without getting back in.
Parked in your driveway and need to move it three feet so you have space to get the lawnmower out of the garage? Use the remote.
All of these use cases depend on the functionality being fast and hassle-free to use. It works that well about 60% of the time - the other 40% the phone fails to connect to the car, or seems to connect but the car inexplicably doesn't move, or gives a useless "Something went wrong" error message, etc.
I mostly use the summon feature for annoyances such as someone parking too close to me or rain causing a puddle to form around the car.
