NHTSA tested Tesla cars that had radar modules. Tesla has decided to remove the radar modules and use only vision systems. The new vision-only models are not NHTSA certified yet, so the NHTSA had to clarify that the safety certification only applies to vehicles shipped before the vision-only transition. That is, any vehicle with radar is still certified, but the new vehicles will apparently ship untested.
- nradov 5y agoAnd it is possible to meet NHTSA certification requirements for recommended safety technology with vision-only systems. Subaru has done that for years.
- harles 5y agoDoesn’t Subaru use stereo vision though? Having depth cues and not having them seems like a pretty big distinction, and Tesla just removed their only source of depth.
- bradfitz 5y agoTesla has multiple cameras on the front. See: https://www.caranddriver.com/news/a36542541/tesla-model-3-model-y-pure-vision/ https://www.caranddriver.com/news/a36542541/tesla-model-3-mo...
- harles 5y agoMultiple cameras don’t equate to stereo though. As I understand it, the Tesla cameras have too little overlap and the distortion is too great to do proper stereo - it’s 100% monocular depth estimation.
- snypher 5y agoThey don't seem very far apart in the Tesla.. https://st.motortrend.com/uploads/sites/5/2017/07/Tesla-Model-3-front-camera.jpg https://st.motortrend.com/uploads/sites/5/2017/07/Tesla-Mode... The Subaru cameras are either side of the mirror, probably much more effective for stereo vision.
- mtnpuma 5y agoSubaru Eyesight cameras look different though, they’re further apart. See https://images.app.goo.gl/vAJJ7JuV1cmTaymA8 https://images.app.goo.gl/vAJJ7JuV1cmTaymA8
- Forbo 5y agoThey won't know that it meets the requirements until it has been tested, so putting this clarification out in the meantime covers the gap until vision-only testing has completed.
- Alex3917 5y agoTeslas are basically just overpriced knockoff Subarus that don't actually work properly. The independent testing data has shown this for years, e.g.: https://www.caranddriver.com/features/a24511826/safety-features-automatic-braking-system-tested-explained/ https://www.caranddriver.com/features/a24511826/safety-featu...
- wedn3sday 5y agoThank for the clarification, this makes perfect sense.
- headmelted 5y agoIt sounds from reading the article like existing cars with the radar are also losing the features though, to be replaced by camera-based solutions? (I assume to keep consistent with newer models on the road without the radar). I may be reading it wrong - happy to be corrected.
- BoorishBears 5y agoThe story I read on this was new cars losing features until their vision-only equivalents show up

- treeman79 5y agoI’m usually one to not like over regulation. Radar / no radar is a pretty drastic change though.
- t0mas88 5y agoI wouldn't even consider this regulation. This is organisation A asking org B to review their product and put a sticker on it that it passed the tests. Then org A decides to make a different product, so org B clarifies that the new product is not the one they tested and certified. This would still go the same way if org B wasn't a government org.
- moralestapia 5y agoThis is it, period. You make a new vehicle, you have to go through the certification again, common sense tbh.
