    Why are we still doing this? Just fucking invest in mass transit like metro, buses and metrobuses. Jesus

    Also, Note that this is based on waymo’s own assumptions, that’s like believing a 5070 gives you 4090 performance…

    They’re super conservative. I rode just once in one. There was a parked ambulance down a side street about 30 feet with it’s lights one while paramedics helped someone. The car wouldn’t drive forward through the intersection. It just detected the lights and froze. I had to get out and walk. If we all drove that conservatively we’d also have less accidents and congest the city to undrivability.

      Back in February, I took a Waymo for the first time and was at first amazed. But then in the middle of an empty four lane road, it abruptly slammed the brakes, twice. There was literally nothing in the road, no cars and because it was raining, no pedestrians within sight.

      If I had been holding a drink, it would have spelled disaster.

      After the second abrupt stop, I was bracing for more for the remainder of the ride, even though the car generally goes quite slow most of the time. It also made a strange habit of drifting between lanes through intersections and using the turning indicators like it had no idea what it was doing—it kept alternating went from left to right.

      Honestly it felt like being in the car with a first time driver.

        Maybe the reason they crash less is because everyone around them have to be extremely careful with these cars. Just like in my country we put a big L on the rear of the car for first year drivers.

      How long ago was that? Last year I took a couple near Phoenix and they did great, lights or no. The hardest part was dropping me off at the front of a hotel, as people were in and out and cars were everywhere. Still didn’t have issues, just slowed down to 3mph when it had 15 years left or so

    Because they are driving under near ideal conditions, in areas that are completely mapped out, and guided away from roadworks and avoiding “confusing” crosses, and other traffic situations like unmarked roads, that humans deal with routinely without problem.
    And in a situation they can’t handle, they just stop and call and wait for a human driver to get them going again, disregarding if they are blocking traffic.

    I’m not blaming Waymo for doing it as safe as they can, that’s great IMO.
    But don̈́t make it sound like they drive better than humans yet. There is still some ways to go.

    What’s really obnoxious is that Elon Musk claimed this would be 100% ready by 2017. Full self driving, across America, day and night, safer than a human. I have zero expectation that Tesla RoboTaxi will arrive this summer as promised.

      You’re not wrong, but arguably that doesn’t invalidate the point, they do drive better than humans because they’re so much better at judging their own limitations.

      If human drivers refused to enter dangerous intersections, stopped every time things started yup look dangerous, and handed off to a specialist to handle problems, driving might not produce the mountain of corpses it does today.

      That said, you’re of course correct that they still have a long way to go in technical driving ability and handling of adverse conditions, but it’s interesting to consider that simple policy effectively enforced is enough to cancel out all the advantages that human drivers currently still have.

        You are completely ignoring the under ideal circumstances part.
        They can’t drive at night AFAIK, they can’t drive outside the area that is meticulously mapped out.
        And even then, they often require human intervention.

        If you asked a professional driver to do the exact same thing, I’m pretty sure that driver would have way better accident record than average humans too.

        Seems to me you are missing the point I tried to make. And is drawing a false conclusion based on comparing apples to oranges.

          Waymo can absolutely drive at night, I’ve seen them do it. They rely heavily on LIDAR, so the time of day makes no difference to them.

          And apparently they only disengage and need human assistance every 17,000 miles, on average. Contrast that to something like Tesla’s “Full Self Driving” (ignoring the controversy over whether it counts or not), where the most generous numbers I could find for it are a disengagement every 71 city miles, on average, or every 245 city miles for a “critical disengagement.”

          You are correct in that Waymo is heavily geofenced, and that’s pretty annoying sometimes. I tried to ride one in Phoenix last year, but couldn’t get it to pick me up from the park I was visiting because I was just on the edge of their area. I suspect they would likely do fine if they went outside of their zones, but they really want to make sure they’re going to be successful so they’re deliberately slow-rolling where the service is available.

            True I just checked it up, my information was outdated.

      What’s more efficient?

      In terms of getting to an exact location.

      Public transportation only can get you near your target mostly. Not on point like a car, bike etc.

        Bicycles? ride/ walk to were you need to be? Why do you need to be driven to an exact point? All the space needed for parking is just wasted.

        You need to create a specific scenario in order to make cars seem more efficient than alternatives. They cause more accidents, take up more space while carrying fewer people at any given time while also causing more pollution than other modes of transport.

          Automated vehicles are GPS guided. The US is too big to be walking and biking. That is for an urban environment with proper zoning laws, proper planning, and serves what amounts to be an ethnic group who shouldn’t need cars. What makes automated vehicles more efficient is the removal of labor and lower operational costs. The specialization of transporting people to the exact GPS coordinates is much more convenient. The future is automated travel because vehicles can be used more productively on the margin than everybody having to own their own car. Fewer cars, higher use of the car, or less idling, means lower transportation costs throughout, which includes infrastructure itself; the less need for insurance, less pollution, etc. This technology can be used in bus transit but in a potentially dynamic way.

            The “US is too big” is such a bullshit excuse since cars are absolutely crap for long distances compared to trains people already walk and cycle in the US. And why is the richest and most powerful (for now at least) country in the world unable to fix it’s zoning laws? Especially since other countries seem to be able to do it.

            Yes, efficiency in reducing the amount of people with jobs but not by getting people from a to b. What is convenient is not having to own a car in the first place and be able to get around with ease because of proper urban planning.

            The future is automated travel because vehicles can be used more productively on the margin than everybody having to own their own car. Fewer cars, higher use of the car, or less idling, means lower transportation costs throughout, which includes infrastructure itself; the less need for insurance, less pollution, etc. This technology can be used in bus transit systems as well for a less marginal benefit.

            Sooo like a what’s already possible with trains and trams? And buses on dedicated lanes would be far easier to automate and be more efficient than cars.

              Trains are for long distances. Trams are for pure urban areas. Metros are for connecting cities within a metropolitan group. All those function within a well planned urban structure, not the suburbs, or exurbs. Cars are the most efficient in the US. That is why most Americans own a car. Without a car, you are asking for long walking distances, and long bike rides. City transit systems don’t work in the US, because too many criminals are out in public, people like their own space, and Americans like the convenience of going, and leaving at their own time. Americans like their own space. Again, you are talking about a specific type of living that most Americans don’t really gravitate to. Americans want a large house in a safe neighborhood in the suburbs, or live in the exurbs. They don’t want to live in crime-ridden urban areas, that is not the American dream.
