  • Now you have phantom braking.

    Phantom braking is better than Wyle E. Coyoteing a wall.

    and this time with no obvious cause.

    Again, better than not braking because another sensor says there’s nothing ahead. I would hope that flaky sensors is something that would cause the vehicle to show a “needs service” light or something. But, even without that, if your car is doing phantom braking, I’d hope you’d take it in.

    But, consider your scenario without radar and with only a camera sensor. The vision system “can see the road is clear”, and there’s no radar sensor to tell it otherwise. Turns out the vision system is buggy, or the lens is broken, or the camera got knocked out of alignment, or whatever. Now it’s claiming the road ahead is clear when in fact there’s a train currently in the train crossing directly ahead. Boom, now you hit the train. I’d much prefer phantom breaking and having multiple sensors each trying to detect dangers ahead.


  • Well, Waymo’s really at 0 deaths per 127 million miles.

    The 2 deaths are deaths that happened were near Waymo cars in a collision involving the Waymo car. Not only did the Waymo not cause the accidents, they weren’t even involved in the fatal part of either event. In one case a motorcyclist was hit by another car, and in the other one a Tesla crashed into a second car after it had hit the Waymo (and a bunch of other cars).

    The IIHS number takes the total number of deaths in a year, and divides it by the total distance driven in that year. It includes all vehicles, and all deaths. If you wanted the denominator to be “total distance driven by brand X in the year”, you wouldn’t keep the numerator as “all deaths” because that wouldn’t make sense, and “all deaths that happened in a collision where brand X was involved as part of the collision” would be of limited usefulness. If you’re after the safety of the passenger compartment you’d want “all deaths for occupants / drivers of a brand X vehicle” and if you were after the safety of the car to all road users you’d want something like “all deaths where the driver of a brand X vehicle was determined to be at fault”.

    The IIHS does have statistics for driver death rates by make and model, but they use “per million registered vehicle years”, so you can’t directly compare with Waymo:

    https://www.iihs.org/ratings/driver-death-rates-by-make-and-model

    Also, in Waymo it would never be the driver who died, it would be other vehicle occupants, so I don’t know if that data is tracked for other vehicle models.



  • The moment you go protest something the government or a company is doing that’s ethically or morally wrong or disadvantages the working class, you get beat up by police and thrown in jail. How is it different?

    Because that doesn’t happen as a rule. Sure, sometimes it happens, especially if the protesters are violent. But, it’s perfectly normal to have an anti-government protest where the cops just stand and watch. Look at all the No Kings protests in the US, and how almost nobody was beaten up or arrested. Millions of people out on the street protesting, only a handful of injuries and arrests.

    Or if you talk bad about a company you get sued for slander for millions of dollars to shut you up.

    Which also only rarely happens. When it does, you can defend yourself in court, and sometimes if your case is a big one the ACLU or EFF or someone will step in on your side to help defend your right to say things. Compare that to an autocratic country where critics of the government or businesses that are cozy with the government often simply disappear and never reappear.

    But, none of that is really what makes an authoritarian government different. What makes it different is that you can’t change that government. Modern western democratic countries that use a mix of socialism and capitalism (so, all of them) have elections. Those elections may not always be fully free or fully fair. But, they exist and they’re not just for show. Surprise results happen. People who have no connections to money or the establishment sometimes gain power. In authoritarian systems that simply doesn’t happen. There are sometimes struggles for power at the top. But, the ability for the people on the ground to influence the way they’re governed is extremely limited. It’s what defines an authoritarian government.


  • Not just lower, a tiny fraction of the human rate of accidents:

    https://waymo.com/safety/impact/

    Also, AFAIK this includes cases when the Waymo car isn’t even slightly at fault. Like, there have been 2 deaths involving a Waymo car. In one case a motorcyclist hit the car from behind, flipped over it, then was hit by another car and killed. In the other case, ironically, the real car at fault was a Tesla being driven by a human who claims he experienced “sudden unintended acceleration”. It was driving at 98 miles per hour in downtown SF and hit a bunch of stopped cars at a red light, then spun into oncoming traffic and killed a man and his dog who were in another car.

    Whether or not self-driving cars are a good thing is up for debate. But, it must suck to work at Waymo and to be making safety a major focus, only to have Tesla ruin the market by making people associate self-driving cars with major safety issues.



  • And, we humans have built-in binocular vision that we’ve been training for at least 1.5 decades by the time we’re allowed to drive.

    Also, think about what you do in that situation where there’s a weird shadow. Slow down, sure. But, also move our heads up and down, side to side, trying to use that powerful binocular vision to get different angles on that strange shadow. How many front-facing cameras does Tesla have. Maybe 3, and one of those is mounted on the bumper? In theory, 3 cameras could give it 3 different “viewpoints” for binocular vision. But, that’s not as good as a human driver who can shift their eyes around to multiple points to examine a situation. And, if one of those 3 cameras is obscured (say the one on the bumper) you’re down to basic binocular vision without even the ability to take a look from a different angle.

    Plus, we have evidence that Tesla isn’t even able to use its cameras to achieve binocular vision. If it worked, it shouldn’t have fallen for the Wile E. Coyote trick.
