    I think it is unsupported aggrandizement.

    Almost nothing to do with what car he chose to make 'self driving'.

    are you serious jumbo?

    that guys a genius, and these cars will be on the road en masse, sooner than later.

    and i'll be glad when it happens. no more traffic jams, no more accidents, maiming, deaths.

    no/low insurance

    I cannot be impressed without a better understanding of the regulatory and safety oversight. Before this can be rolled out to consumers, the required levels of software verification and fault handling and crash prevention are quite high, but none of this is addressed in the article.

    Put another way, don't bother showing me one successful cross-country trip. I need to see how the system can produce and verify a mortality rate of under 1 death per 100 million vehicles miles traveled, with a roadmap in place for pushing that rate down to less than 0.1 death/100MVT.

    what is the current rate

    1.25/100VMT.

    But that is with the current mix including a lot of dangerous drivers and driver behaviors. I'm sure that the good drivers within the mix are considerably safer than that. Autonomous vehicles need to aim to at least match the good ones, hence the near-term 0.1 target. Plus a longer term target for 0.01.

    On this scale, commercial airlines are now about 0.002. But they normally use a different scale based on departures or flight segments, not miles.

    idk, if it saves one life, it's worth it

    When spending billions of dollars, I want to see far more than one life saved. Otherwise, that money can save far more lives by spending it on other safety systems.

    With a GDP of only $20 Trillion, and annual deaths running at 2.6 million, we simply don't have the resources and GDP to be spending a billion dollars to save a single life. In general, we shouldn't be spending much over $7 million per life saved, because doing so takes resources away from saving more lives elsewhere.

    Doesn't matter. Even funds taken from 'worthless' spending should be funneled to things that save more lives per dollar spent. And there is a lot of low lying fruit out there.

    U.S. traffic deaths have exceeded 40,000 per year for several consecutive years, and serious injuries exceed 4 million. Anything that can take a significant bite out of that, say a 10% reduction, is worth many $billions.

    true, but won't be. so if this guy can swing it, good luck to him. probably save more than one life

    When these systems are actually ready, they should save many lives.

    But they shouldn't be permitted for consumer sales as autonomous cars until they can at least match the average fatality rate of human drivers. And considering how many drivers are already abusing current driver-assist features, mentally disengaging with systems not sufficiently safe for such use, it is not at all obvious that the next round of 'autonomous' systems will be good enough to save any lives. If they promote too much driver disengagement, too soon, they could well cost many lives.

    agreed. they need to be driver less.

    My two cents:
    1. My first thought is "He has balls to be the one behind the wheel", even that he created the system himself. Why? Prius doesn't have much long ranger sensor other than the sonar behind the emblem. So I can picture in various scenarios this system will lead into an accident without machine making any mistakes.

    2. Don't be confused with the meaning of this. This is not even a prototype or demo. POC (proof-of-concept) at most. I'd call it showboating. It's at a boundary between being genius, which he is, and reckless (his career has a good track of this too). But still as an engineer in the same field I salute that bravery.

    3. IMO Prius is not a capable car for self-driving, even if Toyota wants to retrofit. Also, to have a higher level of autonomy to pass various Functional Safety standards is a lot harder than put down a smart machine learning algorithm in a powerful compute engine.

    4. The true reason I want to share this is comparing to comma.ai this seems to reach another level of autonomy. I could be wrong but there seems to be no sign tapping into the CAN bus from windsheld. I am curious where else we can tap into the CAN bus. Really amazing work I'll say...

    Banning all cars will save many lives. Is it worth it?

    Proof of concept was done back during the DARPA Grand Challenge, more than a decade ago. The industry is beyond that now.

    lets ban cell phones first, and see how it works out

    These DARPA thing never got tested on the actual street. It is also using a very primitive approach to perform obstacle avoidance. (I remember coding all these before). This is the POC that you can use a off-the-shelf consumer electronics hook into the CAN bus to survive actual street test. That potentially proof the after-market for autonomous driving is possible. It's two completely different things.
