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.
Tesla self driving is never going to work well enough without sensors - cameras are not enough. It’s fundamentally dangerous and should not be driving unsupervised (or maybe at all).
Five years ago, you could not have brought this up without Musk simps defending it.
as daily rider, i must add having a tesla behind to the list of road hazards to look out
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.
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.
