    Many will run a machine tool without the proper PPE for years and not get hurt so they trust. It takes rules and boss to make them do the right thing.

    The liability end of this has scared the shit out of automakers for many decades. I know GM had SDVs in test in the late 70s and early 80s. Yes before there was a IBM PC.
    Some even semi trucks and you could throw a dummy out in front of it and it stop.

    I do understand what level 5 is and we have a very long way to go to get there. Personally I think it not achievable even 100 years out.
    Maybe we can get close but it's like steeping half the distance to a wall, you never get to the goal.

    One thing I've heard spoken is that it's no problem, if the system gets confused just have it pull over and stop.
    I said, "Have you every tried to pull over to the side of freeway in Atlanta during rush hour?"
    Bob

    In Atlanta rush hour, you don't have to pull over to the side of the highway to stop, all 8 lanes are already stopped.

    LOL, I always time my trips from Michigan to Florida and back so that I hit Atlanta between 3 and 4 in the morning.

    When I was attending Georgia Tech and regularly driving between Florida and Atlanta, I wouldn't leave from Florida until 7 or 8 at night, so that I'd be getting into Atlanta around 2-3AM...

    I wouldn't pull over to the side. That's where the buses go to pass the stopped traffic !

    To tell the truth, I don't understand all this brewhaha over self-driving vehicles ? What's the point ? If you don't want to drive, get on the streetcar. Seems very much like an "answer" in search of a problem, to me. One where the answer is going to be worse than the problem.

    That is exactly how I see it. It seems to be a push for SDVs rather than a demand from the public. They paint a rosy picture of an SDV future and gloss over real problems and drawbacks. Some of it seems to be greed from those who want to eliminate paying professional drivers while other aspects hint of a social agenda.

    Right now when a taxi or ride share picks up an elderly or handicapped person the driver usually helps them into the vehicle and then places the walker or whatever into the trunk or rear cargo area. They reverse the process at the destination. How is the software going to get out and provide similar assistance?

    Many delivery drivers, including the guys who haul a trailer full of beer also unload and bring it into the store with a hand truck. Again, how is a driverless vehicle to do that. One of the reasons drivers unload is because these are split loads for multiple customers and they don't want the customer's employees touching merchandise inside the truck.

    Really? We have to explain the value of owning your own car or truck. I’m supposed to take a streetcar from Chicago to Des Moines? Which line would that be?

    If SDVs were available I’d buy one. I’ve driven a Tesla in self driving mode “assist”. Problem is for me at least it is very difficult to pay continuous attention when you aren’t actually driving. I hope they find a way to make certain routes available for SDVs. Go from Chicago to Omaha in SDV mode. Then switch to Manual as you get off the freeway.

    Try driving Melbourne-Sydney or even worse, Adelaide-Perth. Long boring distances that just have to be covered.

    Good luck with the street car - better have plenty of books to hand while you wait for one to come along though.

    Viable self drive electric cars are the missing link for succesful car sharing........not for everyone ,maybe,but a solution to car ownership problems for those who have no parking facilities in big cities.....Mandated by governments as an alternative to spending billions on road networks .I see the concept really taking off in the near future.

    There is different types of driving and ranges.
    I have long wanted a car or truck that could do 4-8 hours north in wide open roads while napping.
    This would make weekend trips nicer and more often.
    Like a train car you could just relax and nap or not.
    Imagine if you could do this from one coast the other. The car would refuel all on it's own on the trip and stops when you wanted to get out and pee or wanted food.

It is not about COMPETING with professional drivers but rather about being able to operate anywhere, anytime, in any weather in the same world where humans have driven for over a century. That world includes not only vehicles and people but also animals, fallen tree branches, and wind blown debris including trash barrels. It is a world where rain, snow, and wind make things difficult and change the normal rules. It is also a world where construction work and temporary obstacles radically change the driving rules. Will an SDV be able to reliably identify the cop on detail and recognize and obey his hand signals? Many times a city lane is blocked for construction or utility work and a cop directs those in one direction to stop while he waves the others through. For those traveling in the direction that is blocked they must proceed into the lane where normally it would be wrong way driving, a violation of the rules.

    On the subject of safety and the oft-repeated claim that switching to SDVs will drastically reduce injuries and fatalities advocates are pushing a false assumption that the MAJORITY of drivers are dangerous. The majority of drivers actually do a pretty good job under often challenging conditions and it has long been known that a small minority of drivers cause the majority of the carnage. Most serious drunk driving accidents involve alcoholics and hard core power drinkers who tend to be repeat offenders and most reckless driving accidents involve a small group of drivers who refuse to accept any limits on their behavior. These are the type who will often continue to drive even after their license is suspended or revoked, and even jail time only temporarily removes them from the roads until they kill someone.

    The notion, repeated here and elsewhere by SDV advocates that humans are too dangerous to be allowed to continue driving after SDVs become common is a dangerous assault on the concept of human liberty, and the likelihood that in the long term we will even be allowed to OWN personal SDVs does not look good if you read what many environmental advocates are saying.


    In a future post I will go into how a switch to SDVs will not eliminate human error and why the issue of modern computers, operating systems, and software WILL be a factor in real world SDVs. In the meantime, here's a hint.


    The CityLab article raises an interesting question of accepting "reasonable" casualty rates.

    What I find intriguing is that with current human operated automobiles we accept present accident and fatality rates without too much thought to it. At the same time we are concerned with accident and fatality rates of ADVs even though they are at likely lower rates then the human driven vehicle rates.

    Now if we compare these reactions to how the public has reacted towards the Boeing 737Max problems, I see a major disconnect. It appears that we as humans are more willing to accept increased risks if we are in control and would find rates that are significantly less in situations that we are not in control unacceptable.

    I suspect a major component to this disconnect is that we tend to view ourselves as having a sense of immortality and that only accidents happen to other people and not us when we are in control. At the same time we demand absolute perfection from automated systems designed, built, and maintained by fallible humans.

    Another major component to this is that we culturally require the suppliers of products to be totally safe and will punish them financially through litigation. At the same time we tend to be more tolerant of individual failures and do not subject individual failures to the same standard.

    This will require a paradigm shift in how we view fault tolerance and liability.

    When all city traffic is limited to 15mph,the share cars wont kill anyone when they collide,if indeed they do .Problem solved in many ways....The SDVs wont need traffic lights ,they will seamlessly move without stopping,thereby ,producing a trip time less than conventional driven cars with all the stops and delays.

    Right. You guys have absolute shit for public transportation, and it makes no sense. Around town cars make sense. For going 500 miles they do not.

    But y'all killed what made sense, trains. Now you want "self-driving vehicles" to accomplish what's already there, except falling apart through neglect.

    I can walk out the door at 7:00 a.m. and be in downtown Beijing, 800 miles away ? in the afternoon. No muss, no fuss, no self-driving car crashing into a trailer because it thought it was a cloud, get up, walk around, eat a snack, take a nap, oogle the girls, lovely. Self-driving vehicles are a half-ass solution in search of a problem that was solved 100 years ago.

    US has a third-world transportation system. May as well be in Africa.

    You take the bus or the train if you do not want to drive or have no car.
    Google it.
    Now if you want to go to Copper Harbor here in the yoouper country options get more limited once you pass the normal stops.
    The last bit is the most expensive and I'm sure in remote areas anywhere in the world this is true.
    One can not compare "served" areas to remote in mass transit.
    Flint to downtown Chi-town, the train ride is kind of cool although most do not consider it. No complaints at all and you spend some other money maybe getting around the town.
    Being a wide open corn field midwest guy this was a new experience and surprised how you can get just about anywhere for very little money.
    There is this whole series of inside running around this city that you can tour.

    That is the thing, easier to jump in the car and you have transportation when you get there even if you spend more money.
    Make no doubt, since the 70's I drive my car, van, motorcycle or truck from here to the south end of Florida non-stop so 21 hours plus behind the wheel.
    (I just simply love Florida coast be it Daytona or Naples... the sound and feel, lay me out at night to die....)
    I always have a spare driver but I like to drive and have never rolled over.
    A SDV would be cool,....Maybe when I get older....

    Spoken by someone who lives in a country smaller than many US states. It appears you don't have any concept of the size of the USA, or the vast distances from place to place in the center of the country. Public transportation requires riders, and much of this country doesn't have any.

    Pretty sure that no state is larger than China, in fact, the whole USA is smaller than China.

    Bwahahahahahaaaaaaa.

    He lives in China. China is bigger than the USA, hard though it might be for you to accept such a thing.

    And yeah, public transport is mainly a function of population density if you want it without truly eye-watering public/tax subsidies.

    A very high percentage of the population lives in an area around a metropolis. A very high percentage of those people's trips could effectively be served by public transportation.

    No one wants to run a subway in Montana or North Dakota

    I live 10 miles from a metropolis(sort of) ,and I can see empty public transport busses going past all hours of the day or night....How much would be saved if self driving cars could pick up the one or two passengers on demand,with busses only needed at peak usage .self driving busses.

    China desn't have subsidies because The People own everything

    But I wonder about that statement. A hundred years ago there were public roads but they were shabby. There were private railroads which made a profit and carried thousands of people (yet with a population density half as much or less than today.)

    Then the goobermint stepped in with public / tax subsidies and built the interstate freeway system. GM and Goodyear et al destroyed the public transportation that was in place. Most cities now would be in heaven if we had the public transport that was in place in 1890. Wouldn't it be more accurate to say that without tax subsidies, public transportation would be the only systems that supported themselves ?

    What does Caltrans cost every year ? How much tax is there on a gallon of gasoline ? What is the cost of white flight ? How much does it cost to bury the best farmland in the world under eight-lane freeways ? Autos are subsidized up the wazoo, saying that public transport requires subsidies ignores the fact that autos are more heavily subsidized than urban and interurban transport ever was. All those systems that got decimated in the thirties were private and got no subsidies. They were decimated by government subsidies to the car.

    I spent the summer fooling around in BC and the northwest. Did not buy a car. Used public transport everywhere. Except for carrying lumber and bottom paint (did that on the bus once, admit it was a mistake, that stuff is HEAVY !) public transportation was not only workable, it was more pleasant. Had some downsides but for a great deal of the time you don't need a goddamned car. In fact I was happy to not have a goddamned car with everything it entails. I saved money and had a better time. And lost some unsightly fat, too ...

    imnsho opinion, self-driving shit is a waste of energy. Cars in general are bad for society. Putting our efforts into better methods of going places and moving things around would be more effective / positive / helpful / whatever. Cars are good sometimes. But like the guy with a hammer, not everything is a nail.
