I'm fairly critical of Tesla in general because they're selling snake oil, with the full self driving promise and whatnots, but this particular critique target

I'm fairly critical of Tesla in general because they're selling snake oil, with the full self driving promise and whatnots, but this particular critique targeted uniquely at tesla seems misguided since every other System of highway assist whether with LiDAR or Doppler radar ignores stationary objects
- totalZero 7y agoStack several technologies together instead of relying on just one. Edge cases will be more easily identifiable because one technology will have high confidence about an obstacle that another does not perceive.
- LoSboccacc 7y agothat works up to a point. if lidar and radar don't detect an object, but stereo vision do, what do? you use consensus, or you go with at least one sensor. there's a lot of tradeoffs involved, including stacking false positives.
- MengerSponge 7y agoEyeSight (Subaru's assistance system) uses stereoscopic cameras, so it can handle large stationary objects. LiDAR can distinguish between on and off-road objects, so it doesn't have to ignore stationary objects. I don't know of a LiDAR-based highway assist that's commercially available, though. Finally, because we're a bunch of pedants here, radar-based systems will register stationary objects that were formerly moving. This is how "follow to stop" systems know when to stop. :)
- sweetbacon 7y agoI was wondering, as I use EyeSight on my Outback and it seems to detect plenty of stationary and odd shaped objects (like an old, empty flatbed semi with broken tail lights) which I didn't expect it to.
