We should all think twice before taking a company PR statement completely at face value and praising them for slowing down faster than their own internal "model" says a human driver would. Companies are heavily interested in protecting their bottom line and in a situation like this probably had 5-10 people carefully craft every single word of the statement for maximum damage control. Surprised at how many comments he…

> Surprised at how many comments here seem eager to praise Waymo based off their PR statement.

Really? My impression is that, for the most part, HN consistently sides with the companies. I say this in the most neutral way possible.

> I've read studies saying that most drivers don't brake at max effort, even to avoid a collision. Ha! It is unbelievable how difficult it is to make someone brake hard. You'd think it's the easiest thing possible in the age of ABS - just press hard as you can. I have a lot of experience on this, I used to teach car control both to teens and adults. One of the frequent exercises was seemingly very simple: Drive at Xm…

If you brake too hard, you might fly over the handlebars.

These training sessions were on cars only, but on motorcycles yes that is possible.

That's my thinking as well. Taken in some abstract scenario, all those steps seems very reasonable, and in that abstract scenario we can even say it would do better than an average human would. But that is missing the overall context that this was an elementary school during drop-off hours. That's when you crawl at 3 mph expecting kids to jump behind any car, and not going at 17mph.

Indeed. Sure the car knows the limit, it knows it is a school zone, it can precisely track people within the reach of its sensors (but not behind blockages it can't see through).

Urm, ime people frequently drive significantly over the speed limit in all these places, at all times of the day.

Blows my mind how you guys confidently state this with authority as if that's the normal behavior, when the reality is that it probably should be - but isn't actually.

So you're confidently stating it's not the normal behaviour... Can you tell me what the average speed is for human drivers outside elementary schools at drop-off times?

An honest account of this situation would place at least some blame on there being a tall SUV blocking visibility. These giant SUVs really are the worst when it comes to child safety

What I find a bit confusing is that no one is putting any blame on the kid. I did the same thing as a kid, except it was a school bus instead of SUV, and that was a fucking stupid thing to do (I remember starting to run over the street, and the next thing is that I am in the hospital bed), even though I had been told to always cross the street from behind the bus, not in front of it. That day I learned why it was so.

Of course the kid is at fault. But everyone knows that kids do stupid and reckless things, which is why drivers are generally expected to take more care around schools and similar institutions. If robotaxis are not able to do that, then the results will be easy to predict

>they're safer because they're less safe Roundabouts are safer. They're safer because they prevent everybody from speeding through the intersection. And, even in case of an accident, no head-on collisions happen in a roundabout.

They're safer specifically for vehicles, as they convert many conflicts that would be t-bones (worst for passengers) into getting rear-ended (maximum crumple zone on both vehicles). Roundabouts are worse for land use though, which impacts walkability, and the safety story for pedestrians and bike users with them is decidedly not great as well.

> and the safety story for pedestrians and bike users with them is decidedly not great as well.

The what now? Seriously, what in the world are you talking about? Roundabouts are heaven. They physically force drivers to slow down when approaching or leaving them, creating a safe environment for pedestrians and cyclists.

For example, there's no such thing as "running a red light at full speed" at a roundabout, no speeding up to "make the light", etc.

For cyclists specifically, they're amazing, because they eliminate the deadly left-turns. Every turn is a right turn, which is super safe.

If you drive in Sweden you will occasionally come up to a form of speed reduction strategy that may seem counterintuitive. They all add to make driving harder and feel more dangerous in order to force attention and lower speed. One is to merge opposite directional roads into a single lane, forcing drivers to cooperate and take turn to pass it, one car at a time. For a combined car and pedestrian road (max speed of 7k…

I recently visited a friend that lives in Sweden (couple hours south of Stockholm). Something he said while I visited stuck with me: "Sweden hates cars." There must be a happy medium somewhere in between.

> prioritizing safety over convenience this sounds like exactly the right tradeoff, especially since these decisions actually increase convenience for those not in cars

Of course it sound right, because you cut off the word "runaway". It is possible to go too far in either direction.

It is, but it's laughable to suggest it's happening anywhere. Our world is dominated by cars. You likely can't see it precisely because it's so normalized.

Does it actually work though? Many roads in London have parked cars on either side so only one can get through - instead of people cooperating you have people fighting, speeding as fast as they can to get through before someone else appears, or race on-coming cars to a gap in the parked cars etc. So when they should be doing 30mph, they are more likely doing 40-45. Especially with EVs you have near-instant power to q…

Does physics work? If it does, then these physical obstacles work too. Go ahead, try to drive faster than 10mph through a roadway narrowed so much it's barely wider than your car, with curbs. And yeah, I'm describing a place in London.

What an American framing. My convenience at the cost of your eventual safety. I guess this is why we also have toddler death machines with 5-foot grills that we call “full size” vehicles.

If you've ever driven more than 5 miles an hour, you risked hurting someone for your convenience. Acknowledging life has risk tradeoffs doesn't make you an American, but denying it can make you a self-righteous jerk.

In many civilized countries and locales, even bringing up the word “convenience” in the context of road safety would be considered tasteless. Maybe a phrase like “excessively obstructive” or other euphemisms would be used, but the word “inconvenient” regarding safety measures that would e.g. help prevent the death of toddlers today would be appalling.

There’s this techbro utopia mindset leaking through as well, just like it does for climate change topics, that pragmatic solutions that work for us today are deprioritized because some incredible technology is right around the corner. This is also distinctly American, specifically Silicon Valley, culture.
