Someone else on HN commented this the other day. RSymons RSEV did a comparison[0] of the self-park feature of Tesla's compared to three other cars. All cars nailed the spots they tested flawlessly while the Tesla just straight up didn't see most of the spots. When they moved the cars further and further away so that the spot became more obvious it eventually did see the spot but parked over a foot from the curb

Tesla seems to have a lot of software issues when it comes to "smart" features like these. I wouldn't be surprised if they are indeed worse than the competition, but I'd love to see a similar comparison
