  • This is the plastic bag reference. LIDAR cannot determine mass. A lot of cars were jamming on the brakes several years ago every time a plastic bag floated in front of their field of view. The algorithms were then tweaked in an attempt to prevent a 20 car pileup because the car freaked out about 1 oz of air-filled plastic. Humans make assessments like this on the fly based on our knowledge of physics, an understanding of real-time conditions, and some level estimation. We may even choose to ignore road markings and normal driving rules if we deem the risk too great vs. the risk of causing a secondary incident (pileup, attention of police, etc). This is not to say meat sacks are exactly perfect in these types of analyses either… This is the tweaking the ML engineers are trying to perfect, for all possible scenarios. A difficult undertaking for humans and machines alike.


  • The update corrects an error in the software that “assigned a low damage score” to the telephone pole

    […]

    Waymo vehicle was driving to a passenger pickup location through an alley that was lined on both sides by wooden telephone poles. The poles were not up on a curb but level with the road and surrounded with longitudinal yellow striping to define the viable path for vehicles. As it was pulling over, the Waymo vehicle struck one of the poles at a speed of 8mph

    It seems the vehicle treated the polls as road debris, etc. This is the plastic bag dilemma. Do you treat something you don’t recognize as a sacred object that must be avoided, or drive through it. This comes up a lot with machine learning based identification of objects - everything is given a percentage of assurance of its identity and nothing is ever 100% guaranteed. That’s a statistical property. Also, every item must have a closely related set of images to model that object in that situation. In this case, a bunch of telephone polls with yellow striping around them seem to have confused the car.









  • Your sarcastic response is reductive and dismissive of a serious issue. Political polarization isn’t about excusing harmful behaviors; it’s about recognizing that extreme divisions are tearing society apart. Simply mocking the idea of understanding the widening chasm between “both sides” ignores the reality that effective solutions come from constructive dialogue, not from deepening the divide.

    Political issues are complex and often involve legitimate concerns from multiple perspectives. In s normally functioning society, there aren’t two sides; free thought leads to a continuum of beliefs. Dismissing these concerns with sarcasm doesn’t help. Instead, it perpetuates the very polarization you’re deriding. Real progress comes from engaging with these issues thoughtfully, not from trivializing them with inflammatory rhetoric.

    If you genuinely cared about reducing harm and making society better, you would consider how your words either contribute to the problem or help solve it. If you can’t contribute constructively, perhaps consider that you don’t need to contribute at all?
