Here's the real question, do you trust Uber to do this (or really anything) the right way, or do you think they'll take whatever shortcuts they can? If someone finds a huge bug in the code and says, "Well, we need to completely rewrite this part or it's never going to work. The rewrite is going to take about 10 months." And someone else says "We can hack a patch in that'll work most of the time in a week.". Which road is Uber going to take in this case? I know what their past performance has shown, they'll take the shortcut. Have they ever done things the hard way?

They probably feel like they are doing it the hard way, because their shortcuts keep backfiring.

I don't trust Uber, but I trust statistics. If Uber is statistically safer without human drivers, then pushing it out 10 months early with bugs could save lives. Humans aren't predisposed to trust science over their gut though.

  I agree. It has something about the loss of control- a fear of the headline that reads "Ybar (sic) self-driving car loses control, 317 people dead."

  I trust statistics but I don't trust bad statistics. There isn't a self driving car operator out there that is currently testing their cars in statistically representative conditions. And unless they are, there isn't a statistical methodology out there that can say they are safer. Google, for example, avoids expressways and won't go on freeways, hasn't tested their cars in extreme weather, barely ever sees even bad weather, and is electronically limited to 25mph. I'd be willing to bet the majority of drivers have nearly perfect driving records in those conditions too.

    Curious about the 25mph assertion. I've driven next to Google self-driving cars in Austin in my neighborhood numerous times and it was definitely traveling faster than 25mph.

      Not sure about your case, but sometimes the humans inside take the wheel.

  Imagine a situation in which Uber cars are better than human drivers, but not by a lot. Then imagine some hastily thrown-together patch being pushed fleet-wide that ends up causing crashes in some unanticipated situations. You could imagine quite a lot of carnage happening out there until they're all yanked off the roads and rolled back. Statistics doesn't tell the whole story because it's backwards-looking, not future-looking, and the Uber crashes aren't going to be independent events.
  - notahacker 10y ago
    Statistics of accidents with human drivers also include a lot of humans who are banned from the road and sometimes even imprisoned for not driving safely enough; the average human could and should be driving a lot better than those statistics. And in many jurisdictions, there's an expectation that a commercial driving service is much better than the average person permitted to use a car. If the service aims to reduce transport costs to the extent that vastly more journeys are taken before - which Uber certainly does aspire to - then its autonomous vehicles can significantly increase the numbers dying on the roads even if they actually do have a persistent and statistically significant per-mile safety advantage over human-driven cars. And if I'm a regulator tasked with reducing road deaths, the question I'd be asking wouldn't be "is this car's autonomous mode marginally better than the average driver so Uber can cease paying drivers and hit profitability?", it's "is the human behind the wheel of a car operating in [semi]-autonomous mode no longer preventing a statistically significant number of crashes?" (or "is telemetry suggesting their interventions are actually responsible for more accidents than they prevent?"). Just because a car is a lot safer with a computer behind the wheel than a car with the average person and no computer behind the wheel doesn't mean that permitting autonomous vehicle operators to rely on technology alone is a safety improvement.

  Statistics says that it will take many, many millions of miles driven by autonomous vehicles autonomously before we can know how safe they are compared to humans [1]. And we may never even know for sure. ____________ [1] http://www.rand.org/content/dam/rand/pubs/research_reports/RR1400/RR1478/RAND_RR1478.pdf http://www.rand.org/content/dam/rand/pubs/research_reports/R...

  The one problem I have with self driving cars is that the software is a single point of failure, so one bad patch (one "mistake") could cause millions of crashes

    Presumably you can do canary deployments and things like that. Whether best practices will be followed is another matter.
  - yazaddaruvala 10y ago
    Software bugs haven't been "single point of [entire fleet] failure" for a while. You just need the appropriate processes in place. - Rolling Deployments - Feature Flags - Automated metrics analysis; With automated rollbacks if an issue is detected Where I work, this has been standard for at least 5 years, and we are just building websites.

      Is there any proof that this is standard for Car companies? Tech companies are bound to have good procedures for tech... that's what they do. Car companies? They should be good at car stuff... but... tech stuff? Look at all the angst surrounding the IOT - companies making buggy/hack-able stuff that otherwise make good things - IE Washing Machines, Refrigerators, etc... look at all the stories about how hack-able stuff involving cars is... Personally? I don't have a lot of faith in "Old" companies getting tech right.

Or one of those big appliance manufacturing corporations. If you're talking specifically about computers, software, and electronics, I think IT seems more accurate.

  The notion that if self-driving technology is statistically safer in bulk than humans, then "it wins" is I think highly fallacious (even though it is made here repeatedly and often). We as humans do not judge whether to do one thing vs another on that basis. E.g. we would ban widespread gun ownership in countries that allow it at present (very large numbers of people would not die as a result); we would mandate a basic set of vaccinations in countries that at present do not do that (same outcome); we would fit the passenger seats facing backwards in commercial aircraft (same outcome). The list is endless but we do none of these things because people prefer to judge the risks in some activity or behavior in the context of their own near term pleasure or convenience. Heck we could mandate very simple low-tech driving safety measures for human-driven cars such as top speed limits and a block on driving the wrong way down the freeway.
  - jimmywanger 10y ago
    > we would ban ... we would mandate ... A common misperception is that we could ban objects, or mandate behaviours. We can only impose penalties on the possession of objects, or mandate punishments on certain behaviours. Simply passing laws does not save lives in the short run.

  You build those statistics by putting them both on the road and comparing the results. Personally I'm not willing to put a machine on the road until it's murdered enough people to properly tally up

It seems to me the best way to build a case for autonomous driving would be for Uber, Lyft, etc to give incentives to drivers who have safety features like automatic emergency braking, then quietly build up a database of accident rate statistics. These services could be a great way to collect this sort of data and see which approaches improve safety. I am skeptical of unmanned taxis for reasons having nothing to do with autonomous driving. What do you do if a passenger gets sick, passes out, starts acting violently, has a heart attack, all things regular taxis encounter. Basically, you need a person to monitor the vehicle, passenger and contents even if the car is driving much of the time. Plus also, pleasant conversation if desired.

I'm not monitored when I ride an elevator, how is an automated taxi any different? > pleasant conversation if desired. This is a good point, I'm sure many people will prefer human-operated taxis for the social aspect and possibly for local recommendations.
