This is your city on driverless cars.

A blackout in San Francisco yesterday cut power to traffic lights. Drivers coped; Waymos just stopped moving, often in intersections, stranding passengers and compounding gridlock.

Maybe allowing a private company to flood public space with a massive fleet of unmanned vehicles isn't great transportation policy. (Especially when shit happens. And shit *always* happens.)
On the other hand, we could just let the "disruptors" do exactly what they want. That usually works out fine.

The fact that driverless cars kill + injure fewer people than conventional cars is a genuine plus.

It doesn't outweigh minus of private companies flooding public streets with constantly cruising vehicles that periodically cause gridlock, chaos.

Here's one Waymo messing up dozens of people's day.

There should be zero tolerance for interfering with public transport like this. Any sane community would recognize this as indefensible.

And driverless cars have killed and injured people. (More than we are told about, that's for sure.) What would you do if a Robo-taxi ran over someone you loved? How could you ever find closure?

@straphanger Closure of the company that operates those vehicles sounds like a good solution.

Eine gute Frage, denn die Betreiber werden sich rausreden und am Ende stehen AngehΓΆrige mit nichts da, im schlimmsten Fall wird ihnen nicht einmal geglaubt, dass es ein autonomes Fahrzeug war.

Eine andere Frage ist, wenn der Traum von Autobahnen Fahrzeugen funktioniert und zwar so wie es verkauft wird, dass die Fahrzeuge nie still stehen und permanent rumfahren, dann ist das zwar effizienter als Autos zur Zeit, bedeutet im umkehrschluss aber auch das StÀdte noch Auto zentrischer werden. Denn Betreiber werden Gründe finden, warum FußgÀngerüberwege jeglicher Art den effizienzsfluss stâren und diese Kisten werden permanent 24/7 umerfahren. Es wird keinen Platz oder Zeit geben. Um den Strom an Autos zu durchbrechen. Autos sind das Problem an sich.
@straphanger

@straphanger I would not feel any better if the driver was a person.
The only relevant question is whether driverless cars are more dangerous than human-driven ones, and it is still open.
@straphanger If you're stuck inside one of these things, are you able to get out?
@LillyHerself @straphanger
I’d like to know that too!πŸ€” Also, can they be pushed out of the way by a couple of people (like you would do if your actual car broke down in the middle of the road).
If you can’t do either of those things how do they even pass a safety assessment & get allowed on public roads full of people? πŸ€”

@Su_G There ought to be some kind of 'manual override' panel, perhaps on the outside, that would allow some level of navigation.

@straphanger

@LillyHerself
Yes, good idea. Someone else suggested the Waymos have a rope or chain at the front so they can be towed out of the way.
People getting stuck in them would be worse though, the people must be able to get out.
Hard to believe these things weren’t tested before they were allowed out in public.
@straphanger
@Su_G @LillyHerself @straphanger I find it believable, considering the other variants of self drive are allowed around with a much worse track record. Not acceptable, but believable.
@ignaziop1977 What versions are those? I hope you're not talking about Tesler, because despite their BS marketing, they don't have anything like that, and probably never will.
@wesdym I was thinking uber. The swastikars aren't going around by themselves but people inside think they can and have ended up dead a couple of times.

@ignaziop1977 Much more than a couple. Tesler in fact holds the all-time record for fatalities, of any car ever made by anyone in any country. They're horrible death machines, by any metric you choose. It's only an extremely corrupt government that allows them to keep being made and sold.

Past a certain point (a few years ago, I'd say), people who buy them just HAVE to be stupid. They can't really have any excuse.

@wesdym yeah two is just what I remember from the news

@straphanger

"The fact that driverless cars kill + injure fewer people than conventional cars is a genuine plus..."

This is not true. It is something the industry says, but there is insufficient data to establish that they are safer on a per capita basis across the full range of driving conditions.

@mastodonmigration @straphanger claims from big corporations about what research says should categorically be considered BS, or at best coincidentally truthful.
These statistical sleight of hands reported for AVs remind me of BS claims from corporate education reformers about charter schools and personalized learning software

@mastodonmigration "I choose to believe what I prefer to!"

Okay, fine. But I don't have to listen to it, and I won't.

@straphanger Driverless cars just add insult to injury. The problem, particularly in the U.S., are too many cars in the cities. In Europe more and more cities disincentivise using cars in cities, by turning streets into pedestrian areas, convert streets into biking lanes, restricting parking spots and boosting tramway, bus-lanes, and metro transport.

This is what has to be done. Not adding even more cars that now even don't have drivers!

@straphanger Tram driver could have been a bit more assertive there... I bet an Amsterdam tram driver would have just plowed straight through.

@straphanger "The fact that driverless cars kill + injure fewer people than conventional cars"

There's a saying - if you want to truly understand something, study how it is measured.

@straphanger

After 10 minutes just make it legal for anybody to damage the car in any way they want.

@straphanger

There are too many ways to manipulate the safety statistics of these cars for me to ever believe they are safer. Same with Tesla where they outright misrepresented the facts for their driverless system.

@contrasocial @straphanger Have third-party tamper-proof "flight recorders". Have laws that ensure the data is open (provisions to maintain reasonable anonymity of course).
@straphanger pretty sure that's just a marketing lie too (that they kill/injure less people)

@Ember Pretty sure you actually have no idea. Anyway, here's one credible piece about it:

https://www.consumeraffairs.com/automotive/autonomous-vehicle-safety-statistics.html

That's from nearly two years ago now, and we now know that Tesla data should not be included in such studies, because that company's testimony is either untrustworthy or unreliable. (Big surprise, I know.)

How safe are autonomous vehicles? 2025

Autonomous vehicles could provide a safer alternative to error-prone human drivers, potentially saving lives on America’s lethal roadways.

@straphanger "The fact that driverless cars kill + injure fewer people than conventional cars" is a good argument for trains imo
Or just public transit in general, with well-trained drivers who don't face penalties for going the speed limit
@straphanger I wonder if DLC have less accidents because they drive slowly... is there any study about it?

@mdione They have a lower rate because they're more exactling and less careless -- and pretty much never distracted -- unlike human drivers. Even given their often baffling or ridiculous failure modes.

As far back as probably a decade ago, I said that SDVs don't need to be perfect. They only need to be better than US. And that's a very low bar to meet. (Trains kill people, too, but no one's talking about banning them for that reason.)

@straphanger
Helsinki (Capital of Finland) just went a full year without a single traffic death. No self driving cars needed.

Helsinki just went a full year without a single traffic death

The capital city is Finnish’ed with car-related fatalities.

@straphanger i don't know if "killing and injuring less people" doesn't outweigh "inconveniencing dozens of people". honestly that seems like an insane take

no amount of inconvenience outweighs any amount of death

@straphanger the solution is both prioritizing public transit, bicycles over any private motor vehicles; regulating the shit out of all private vehicles; having zero tolerance on any preventable accidents; and giving no more leeway to driverless cars than conventional ones
@straphanger
Ooh, free raspberry pis
@straphanger
Nothing a copper mesh-lined covered truck bed can't fix.
@jargoggles @straphanger Or a large truck with bumper guards, and lots of power in low gear. "Outta' my way, you piece of shit." <pushes Waymo car to side of street>
@straphanger In theory we need many less vehicles operating within city limits, relying on public transportation, and or a system of rented automated vehicles. That said what we currently have doesn’t work and I like the idea of mayors who propose banning privately own vehicles within city limits, as long as infrastructure exists to support transportation, which might be a solution to the situation you highlighted as long as infrastructure meets the required standard and need.

@straphanger

cars of any sort are not a great transportation policy

@darwinwoodka @straphanger … at least not privately owned within city limits with heavy reliance on a bus/Metro system.
@Huntn00 @darwinwoodka @straphanger Taxis and robotaxis are still cars taking up just much space on the rod as a privately owned car...more, actually, since they are on the road without passengers.
@jhavok @darwinwoodka @straphanger except if for example you have 50k families each with a vehicle replaced by public transportation, in a much smaller network of total vehicles, a mix of mass transit, metro lines, bus and many less hired automated cars.
@Huntn00 @darwinwoodka @straphanger So your theory is that the inconvenience of calling a robotaxi will drive people to public transit.
@jhavok @darwinwoodka @straphanger Dude, I said in theory. I’m not locked into any hard position. At this point, I’d rather hear your solution.
@Huntn00 @darwinwoodka @straphanger My theory is that improving the speed and reliability of mass transit and the walkability of cities will reduce traffic, whereas robotaxis will be traffic.

@jhavok A particular kind of traffic, yes, and your point has been where many fellow SDV advocates decide I'm an asshole and won't talk to me, heh.

The hard reality is that a car is car is a car, and that's just immutable physics. We'll always need them, but we can sure do with WAAAY fewer of them. SDVs can help with that (by moving more people in fewer vehicles), but are only part of larger solution, which in my mind MUST emphasize mass transit.

It's not either/or, though; we'll have both.

@wesdym So now you're imagining the autonomous cars as mini-trams that carry several people on each trip?

@jhavok I think you might be replying the wrong person, but I admit I'm not sure.

What *I* said is that SDVs are PART of the solution to congestion, but mass transit is always preferable.

The larger point is echoing yours, that SDV or not, all cars take up the same space (more or less) and carry the same (not many). We'll have to have them, but the more people we can get out of ANY kind of car, the better.

@jhavok The tech is still in early stages, and for all their sometimes hilarious or infuriating failures, I sense that Waymo's ahead of everyone else, and will sort out more sooner. But right now, it's bound to be weird and often annoying.

In time, a combination of SDVs and mass transit can make a big difference. Neither is inherently better overall, and we can have both.

@jhavok Eh, the math can be tricky. It depends what you want to measure, and why. Transportation experts often talk about 'passenger lane-miles' or the like, which is good for comparing xy space taken up per person per lane per mile travelled, and that's how we know that buses are many times the infrastructure efficiency of private cars. In theory, a taxi is more efficient than a car, because it's used more. Waymo would be the same (when it works, of course).
@straphanger doing this without very strict requirements is absurd, and local voters should send a message to city councils. They can earn money if they show means to deal with emergencies.
And no, "just trying it out" not gonna work.
@peteriskrisjanis @straphanger what’s the economic impact of blocking a lane in a city? Thousands of dollars per minute? So the fine should be maybe 10 times that?
@ShadSterling Holy shit, buddy, get over yourself.
@straphanger πŸ˜‚
artificial yes
intelligence defiantly not

@straphanger

so not one techbro genius thought this would happen

not one

waymo needs to be held accountable for any outcomes - death injury loss of property etc - for shit like this

@samiamsam Pretty much the only way a stopped car can cause any of that is if some moron crashes into it, but okay.
