That magnitude of a difference would be pretty noticeable and I haven't seen Cruiser users posting amazing reviews on YouTube in comparison to Tesla's. Maybe I am using an incorrect proxy, but it's hard to believe that Tesla would be so far off.
Are you kidding? 40k km with no disengagement? This is nuts. I don't think we have reached that level yet. And if we did, I can't believe Tesla engineers would be so oblivious to that that they wouldn't update their technology. The likeliest explanation is that the article's chart is using some weird metric that is not comparable between automakers.
You've given no actual reasons you find this hard to believe, just running on 100% vibes. The data reported to regulators doesn't lie. Tesla really is that far behind the competition.
