This will surely get some skepticism as it's a Waymo study, but it's nice to see a real‐world dataset this large at 56M miles. An 85 % drop in serious‐injury crashes and 96 % fewer intersection collisions is a strong signal that Level 4 ADS can meaningfully improve safety in ride-hail settings. Still curious about how much of that comes from operational design versus the core autonomy, but it’s a big leap beyond “nov…

It's good to be skeptical of the source, but I can't remember seeing any substantive criticism of the methodology or conclusions.

Anecdotally, as someone who bikes a lot in SF, Waymo's are a lot safer than human drivers simply because they follow the letter of traffic laws. Stopping at stop signs, waiting for pedestrians to clear the box, following the posted speed limits, etc.

I was just on a business trip to San Francisco for a few days, and I observed the near opposite of this from the Waymo fleet in SoMa: * Waymo vehicle creeping into the pedestrian crosswalk (while the pedestrians had right of way to cross), which caused someone to have to walk around the car into the intersection ahead of the Waymo. * Waymo vehicle entering a dedicated bike lane and practically tailgating the bicyclis…

> * Waymo vehicle entering a dedicated bike lane.

In California, California Vehicle Code § 21209(a)(3) expressly permits a motor vehicle to enter a bicycle lane “to prepare for a turn within a distance of 200 feet from the intersection” -- among other cases. (The vehicle must yield to cyclists in the lane.)

As someone who is often on SF city streets without a car - I bike and run a lot - I absolutely love Waymo. I am continuously seeing human drivers cut me off, perform illegal maneuvers (i.e. run red lights when I'm going through a crosswalk), and break various other traffic laws. All these things genuinely put people in danger. Just the other day, a guy started running a "no right turn on red" lane in SF, and when I p…

My favorite thing from my first Waymo ride was watching a lady walk up to the middle of the street to cross. The Waymo saw her, slowed, and waited to let her cross. She smiled and waved and immediately felt dumb because who is she waving to? Do I wave back? We laughed at each other as it drove away.

Ever since then my fear melted away. They see every direction, never blink, and are courteous and careful with pedestrians.

I would be interested to see waymo adapt to the snow and ice, where “hit the breaks” Is the wrong answer, and the correct is to drop the car into neutral. I believe waymo will figure this out in time, nut SF and Phoenix are idealized driving conditions.

> snow and ice, where “hit the breaks” Is the wrong answer, and the correct is to drop the car into neutral This is only true with 2WD and no automatic stability control, and if you’re going down a slope. For every other case, ABs will out perform in snow and gentle braking will evenly distribute traction force with stability control doing microsecond evaluations.

It is also the case that Waymo will be dramatically better than all humans in ice because it is going to take the aviation approach and stay in the depot, rather than fooling itself into believing it is competent at driving on ice.

good thing drones are getting smarter

Well sure but drones won't shit, that's why we need the organic piece. I guess they could drop rotten fruit in lieu of shit, but then we need a supply chain to restock the rotten fruit in the drones.

I am also hopeful that Waymo has other positive externalities for bikes/pedestrians: less need for parking spots, car ownership, etc. At the same time, I guess you could say the same for rideshare, so it would depend on if robo-rideshare is cheaper than ownership

My prediction is that car usage will go thought the roof when AI cars work.

People can have a stress-free commute to a nice house in the countryside and work in the cities. Because the car is electric, it will be inexpensive to run.

Neither of the examples you cite strike me as particularly dangerous nor even illegal. The pedestrians were given the right of way. And entering bike lanes is fine for crossing or short distances where merited unless grade separated.

A vehicle that becomes blocked in a crosswalk is unsafe for pedestrians who want to use that crosswalk if it forces the pedestrians to walk around the blocking vehicle. There are crosswalks in SoMa that provide for 45 seconds or more of crossing time. A Waymo that enters one of these crosswalks after 15 seconds into the 45 seconds allocation blocks the crosswalk for the remainder of the 30 seconds. This presents an unsafe situation for all existing and future pedestrians (e.g., a pedestrian who inadvertently steps into the intersection while trying to go around the blocking vehicle).

We also know that in North America that the municipal services skimp on grade separation for bike lanes for budget and political reasons. I did bike in San Francisco when I lived there, and these non-shared colored lanes never ever felt safe.

I can guarantee that if you leave your North American context for a couple of years and come back to it you'll find CA Vehicle Code § 21453 unsatisfactory.
