Your first quote implies that the Tesla autopilot had better than average performance but not by much, when normalized for roads. Like… sure. Who cares? That’s a nuanced statistic that doesn’t even change the direction of the difference. Your second argument… again, sure, whatever? Not a contradiction or evidence of a lie.

Ok lemme slow down and do it one at a time. Remember the battery swap scandal? There were many articles written about it.[0] Turns out it was a conscious scam by Tesla to increase its vehicle credits[1] I've got more, but I think I'd have better luck taking it one at a time so I'll wait... [0] https://dailykanban.com/2015/05/27/tesla-battery-swap-unused... [1] https://dailykanban.com/2015/05/27/tesla-battery-swap-unu…

I don’t care about Tesla much so… no, I don’t know about a battery swap scandal from 7 years ago. But reading this first article (which is the same as the second article) it would appear that Tesla invited people to use a battery swap facility and a team of investigators staked it out for 48 hours and nobody came.

???

What am I supposed to take from this? I think maybe you intended to provide a different article with an actual claim but the first one seems unlikely to matter.

I’d like to see something specific to claims that teslas aren’t actually safer than average if possible

Every autonomous braking system has that problem, including the one in my 2020 Macan. They are dangerously-flaky hacks. As of 2025 they are mandated by law.

Better a false positive (phantom braking) than a false negative (not braking when it should). I imagine they're all tuned with this in mine.

Yes, how about a stat for, "accidents/incidents which were proceeded by AutoPilot disengagement within the past ~5 seconds."

That's what Tesla is counting. From the methodology section of the safety report: > To ensure our statistics are conservative, we count any crash in which Autopilot was deactivated within 5 seconds before impact, and we count all crashes in which the incident alert indicated an airbag or other active restraint deployed.

That's what I get for not reading the source material! Thanks for correcting me.

If it is actually applying the brakes for you more than in cases where you are clearly about to rear-end someone, you should consider not tailgating as much Thanks, Dad. Clearly I have no idea what I'm doing, or what I'm talking about, so my real-world experience is invalid. For the benefit of everyone else, phantom braking is a thing that by definition occurs when you're not following anyone. Such as when the car sl…

I think I meant to add more weasel words to that like "consider". Let me be more direct. In 20k miles in this vehicle, I have never once encountered the radar based AEB warning , not even activating, in a situation where it wasn't obviously sensing a car that would be in the path of my vehicle. It has not activated for trash, or overhead bridges, or cars in the next lane over, or any of the number of things everyone…

I did 30,000 miles in a 2019 outback with a significant amount of phantom breaking, more than I've had in my Tesla or e-tron. Anecdotes don't mean much.
