to be fair, the video can be very biased by cherry picking single incidents. I am a Tesla owner and i LOVE the car, and i both laughed and cringed at the volvo guys royally screwing up something so simple.
I wouldn't want to underestimate the progress that other manufacturers have made just because i "root for" Tesla. Mercedes could have come up with the near perfect algorithm for autopilot and unveil it tomorrow for all i know, and it could blow Tesla's out of the water. What i can observe tho, is how probable this is, and how quick is each manufacturer's autopilot program learning.
Tesla does have a massive, MASSIVE fleet of human driven vehicles on the road that autopilot learns things from, and they don't scale it up by hiring more people to drive the cars around like some sort of UAT, but real world drivers behaving in real world situations, which has massive advantages.
e.g. if you're a programmer, you either decide or get told by a team whether to program a car to do evasive maneuvers for a certain sudden situation. But Tesla can learn from massive real world data, where some would rather brake as hard as possible to take a certain but minimised impact (which, is the ONLY legal way to drive in many countries) whereas others would check for empty space and swerve to avoid the accident. Certain people drive more cautiously and may already have taken their foot off the throttle a bit before something becomes an issue.
What Tesla has, is the massive feed available to them for accurate, real world empirical data instead of some "expert" panel groups who can't possibly consider the whole range of situations that come up. I'm rooting for Tesla, and I think they have an autopilot program that has the best learning potential, regardless of how good they are compared to other car maker's "claims" at the moment.
TL;DR All the non-tesla car makes get the benefit of doubt for their claims of superior autopilot technology, but Tesla has objectively the best autopilot learning platform by far because we're all part of their learning already.
