So as many people are exploring with the new advanced summon, I've had a lot of close calls on my very limited tests, and I don't know whether the close calls were not "close calls" but merely me not trusting in the technology to do what it should do. I, being just to the side of an aisle of cars my car was pulled into, used the advanced summon. It started backing out flawlessly.. until it had turned far beyond the point it needed to as it backed out, in order to stop, turn the other direction, and pull forward towards me. When it got within a foot of the parked car on the other side and didn't look like it was going to stop, I let go of the button and it stopped. I re-positioned myself so I had a better view of just how much clearance it had, and then attempted the summons again. Expecting it to pull forward, instead, it continued on it's rearwards traverse, with me immediately stopping it. It stopped 6" from the bumper of the car behind it. At that point, I decided it was too much of a risk and walked to it. Being computerized, and understanding feet and inches, had I not chickened out, would it have stopped itself an inch from the other vehicles bumper, than turned out, or was I right to stop it where it was? I haven't tried setting up trash cans to simulate the process and see if it hits the trash cans, but a car seems like a large enough, blatantly obvious object to recognize, especially in broad daylight. I tried it again later in the day, where I had backed into a parking spot, to see if it worked better. It did. It pulled out and started driving towards me, until it saw the pedestrian walking towards the store I was at, close to the side of vehicles. Ist stopped about 10-15' short of her and stayed in place. I kept the button pressed, and eventually, after she walked another 3-5 feet, it pulled forward about 1 more foot, then stopped. Then it pulled forward again about 6 inches, and stopped a third time, with an error popping up on my phone stating "error, pedestrian" and failed. It's amazing it can see a pedestrian 15' away and think it's in danger of hitting it, but it can't see a car 6" from it. My last attempt was at night in a parking lot with nobody around. There was a planter between myself and the vehicle, and the curb was painted red. It pulled out of the parking spot and started coming towards me, then suddenly it turned hard right and started turning straight for the curb. I stopped it about 6"-1' from the red painted curb with the car tires turned hard right. Had I not stopped it, it would have most definitely hit the curb! Have any of you used trash cans or cardboard boxes/other items that wouldn't hurt the car, to test exactly how well it detects objects? Would love to hear your results. So far that I can tell, it's an extremely scary feature to use, risking in my case, a $60k car to save from walking 20-30 feet. I can't imagine Tesla repairing my car for free because I didn't let go of the button in time and it slammed into a wall that it should have seen! I'm scared to use the feature at the moment!
