TL;DR: Self-Driving Teslas Rear-End Motorcyclists, Killing at Least 5
Brevity is the spirit of wit, and I am just not that witty. This is a long article, here is the gist of it:
- The NHTSA’s self-driving crash data reveals that Tesla’s self-driving technology is, by far, the most dangerous for motorcyclists, with five fatal crashes that we know of.
- This issue is unique to Tesla. Other self-driving manufacturers have logged zero motorcycle fatalities with the NHTSA in the same time frame.
- The crashes are overwhelmingly Teslas rear-ending motorcyclists.
Read our full analysis as we go case-by-case and connect the heavily redacted government data to news reports and police documents.
Oh, and read our thoughts about what this means for the robotaxi launch that is slated for Austin in less than 60 days.
On a quick read, I didn’t see the struck motorcycles listed. Last I heard, a few years ago, was that this mainly affected motorcycles with two rear lights that are spaced apart and fairly low to the ground. I believe this is mostly true for Harleys.
The theory I recall was that this rear light configuration made the Tesla assume it was looking (remember, only cameras without depth data) at a car that was further down the road - and acceleration was safe as a result. It miscategorised the motorcycle so badly that it misjudged it’s position entirely.
This video proposes that theory.
Ah, thanks for jogging my memory
Are you saying Harley drivers are fair game?
The ridiculous thing is, it has 3 cameras pointing forward, you only need 2 to get stereoscopic depth perception with cameras…why the fuck are they not using that!?
Edit: I mean, I know why, it’s because it’s cameras with three different lenses used for different things (normal, wide angle, and telescopic) so they’re not suitable for it, but it just seems stupid to not utilise that concept when you insist on a camera only solution.
That seems like a spectacular oversight. How is it supposed to replicate human vision without depth perception?
Still probably a good idea to keep an eye on that Tesla behind you. Or just let them past.
I also saw that theory! That’s in the first link in the article.
The only problem with the theory: Many of the crashes are in broad daylight. No lights on at all.
I didn’t include the motorcycle make and model, but I did find it. Because I do journalism, and sometimes I even do good journalism!
The models I found are: Kawasaki Vulcan (a cruiser bike, just like the Harleys you describe), Yamaha YZF-R6 (a racing-style sport bike with high-mount lights), and a Yamaha V-Star (a “standard” bike, fairly low lights, and generally a low-slung bike). Weirdly, the bike models run the full gamut of the different motorcycles people ride on highways, every type is represented (sadly) in the fatalities.
I think you’re onto something with the faulty depth sensors. Sensing distance is difficult with optical sensors. That’s why Tesla would be alone in the motorcycle fatality bracket, and that’s why it would always be rear-end crashes by the Tesla.
In that case, you wouldn’t happen to know whether or not Teslas are unusually dangerous to bicycles too, would you?
Surprisingly, there is a data bucket for accidents with bicyclists, but hardly any bicycle crashes are reported.
That either means that they are not occurring (woohoo!), or that means they are being lumped in as one of the multiple pedestrian buckets (not woohoo!), or they are in the absolutely fucking vast collection of “severity: unknown” accidents where we have no details and Tesla requested redaction to make finding the details very difficult.
Thanks!
At least in EU, you can’t turn off motorcycle lights. They’re always on. In eu since 2003, and in US, according to the internet, since the 70s.
Point taken: Feel free to amend my comment from “No lights at all” to “No lights visible at all.”
I assume older motorcycles built before 2003 are still legal in the EU today, and that the drivers’ are responsible for turning on the lights when riding those.
Whatever it is, it’s unacceptable and they should really ban Tesla’s implementation until they fix some fundamental issues.
