I think my problem is that it reacted after seeing the child step out from behind the SUV. An excellent driver would have already seen that possible scenario and would have already slowed to 10 MPH or less to begin with. (It's how I taught my daughter's to drive "defensively"—look for "red flags" and be prepared for the worst-case scenario. SUV near a school and I cannot see behind it? Red flag—slow the fuck down.)

I don't see how that's feasible without introducing a lot of friction. Near my house, almost the entire trip from the freeway to my house is via a single lane with parked cars on the side. I would have to drive 10 MPH the entire way (speed limit is 25, so 2.5x as long).

It's hard to consider it "lots of friction" in a vehicle where you press a button to go faster and another button to slow down.

A single lane residential street with zero visibility seems like an obvious time to slow down. And that's what the Waymo did.

Vehicle design also plays a role: passenger cars have to meet pedestrian collision standards. Trucks don't. The silly butch grilles on SUVs and pickups are deadly. This is more of an argument for not seeing transportation as a fashion or lifestyle statement. Those truck designs are about vanity and gender affirming care. It's easier to make rational choices when it's a business that's worried about liability making those choices.

"It depends". If 50 people die and 50 people go to jail, vs. 40 people die and their families are left wondering if someone will take responsibility? Then that's not immediately standing out as an improvement just because fewer died. We can do better I think. The problem is simply one of responsibility.

Do they go to jail? That is not my experience here in the Bay Area. In fact here is a pretty typical recent example https://www.nbcbayarea.com/news/local/community-members-mour... The driver cuts in front of one person on an e-bike so fast they can’t react and hit them. Then after being hit they step on the accelerator and go over the sidewalk on the other side of the road killing a 4 year old. No charges filed. This…

Ugh. That is so despicable both of the driver and as a society that we accept this. Ubiquitous Waymo can't come soon enough.

That doesn't mean it can't be solved. Don't drive faster than you can see. If you're driving 6 feet from a parked car, you can go slow enough to stop assuming a worst case of a sprinter waiting to leap out at every moment.

If we adopted that level of risk, we'd have 5mph speed limits on every street with parking. As a society, we've decided that's overly cautious.

But with waymos it would be possible. Mark those streets as "extremely slow" and never go there unless you are dropping someone off. (The computer has more patience than human drivers.)

If that's too annoying then bad parking by school areas so the situation doesn't happen.

A human driver would most likely have killed this child. That's what should be on the ledger.

That's pretty hyperbolic. At less than 20 mph, car vs pedestrial is unlikely to result in death. IIHS says [1] in an article about other things: > As far as fatalities were concerned, pedestrians struck at 20 mph had only a 1% chance of dying from their injuries Certainly, being struck at 6 mph rather than 17 mph is likely to result in a much better outcome for the pedestrian. And that should not be minimized; althou…

There's a 50/50 chance that a distracted driver wouldn't have slowed at all and run the child over.

I mean, you are putting your finger right on the answer: the whole car thing doesn't work or make sense, and trying to make autonomous vehicles solve the unsolvable is never going to succeed.

Yes and no. Tons of situations where this is simply not possible, whole traffic goes full allowed speed next to row of parked cars. If somebody unexpectedly pops up distracted, its a tragedy guaranteed regardless of driver's skills and experience. In low traffic of course it can be different. But its unrealistic to expect anybody to drive in expectation that behind every single car passed there may be a child jumping…

I slow down considerably near parked cars. And I try to slow down much earlier approaching intersections where there are parked cars blocking my view of cross walk entries. I need to be able to come to full stop earlier than intersection if there happens to be a pedestrian there.

> Waymo said its robotaxi struck the child at six miles per hour, after braking “hard” from around 17 miles per hour. The young pedestrian “suddenly entered the roadway from behind a tall SUV, moving directly into our vehicle’s path,” the company said in its blog post. Waymo said its vehicle “immediately detected the individual as soon as they began to emerge from behind the stopped vehicle.”

As this is based on detection of the child, what happens on Halloween when kids are all over the place and do not necessarily look like kids?

Orders of magnitude? Something like 100 people die on the road in the US each day. If self-driving tech could save 10 lives per day, that’s wouldn’t be good enough?

Then that's not immediately standing out as an improvement just because fewer died. We can do better I think. The problem is simply one of responsibility.

Apart from a minority of car related deaths resulting in jail time, what kind of person wants many more people to die just so they can point at someone to blame for it? At what point are such people the ones to blame for so many deaths themselves?

How do you add a chain link fence between the parked and driving cars for on-street parking?

there's still an inlet and outlet (kinda like hotel pickup/drop off loops). It's not absolutely perfect, but it constrains the space of where kids can dart from every parked car to 2 places. Also the point isn't the specifics, the point is that the current design is not optimal, it's just the incumbent.

Ok, that's not really a simple change anymore, because you need more space for that. Unless it's really just a drop off queue, but then it's not parked cars, since a parked car blocks the queue.

We would really need to see the site to have an idea of the constraints, Santa Monica has some places where additional roadway can be accomodated and some places where that's not really an option.
