Waymo 13x safer than human drivers
Our new safety data is in đ Over 170M miles through Dec 2025, the Waymo Driver was involved in 13x fewer serious injury or worse crashes than human drivers in those same cities. At our current scale, that means preventing a serious injury crash every 8 daysâa real, positive
Anecdotally, both from riding in them and walking/driving next to/around them, this feels obvious. They never get distracted. Sure, they sometimes make mistakes, but the mistakes are never "I didn't see that". They see better than humans in all cases (where they operate). They react faster than humans.
The one case where they hit a child, it was because the child jumped in front of the car. And they showed that they hit the child at a lower speed than a human would have because of the reaction time.
I would rather be in an area where only Waymo's are allowed than an area where they are banned.
Waymo saved my life in LA.
When I visited LA, I rode in a Waymo going the speed limit in the right lane on a very busy street. The Waymo approached an intersection where it had the right of way, when suddenly a car ignored its stop sign and drove into the road.
In less than a second, the Waymo moved into the left lane and kept going. I didn't even realize what was happening until after it was over.
Most human drivers would've t-boned the car at 50+ km/h. Maybe they would've braked and reduced the impact, which would be the right move. A human swerving probably would've overshot into oncoming traffic. Only a robot could've safely swerved into another lane and avoid the crash entirely.
Unfortunately, the Waymo only supported Spotify and did not work with my YouTube Music subscription, so I was listening to an advertisement at the time of my near-death experience. 4.5 stars overall.

This detail sent me, it's crazy that we can pay $25 to have a life saving robot take us across the city yet Spotify is going to blast ads at us the whole time for the sake of making an extra $0.18 (yes that's the actual number) per hour of listening time.

Oh, the self driving car business will get there, believe me. This is just the first iteration. Designed to get everybody on board with the idea.

You'll probably never forget that advertisement, which is an exciting business opportunity for Waymo.
They could partner with Spotify and other media content partners so that the Waymo can generate an adrenaline-rush near crash experience when a premium advertiser's ad is playing. /s (hopefully)
It looks like YouTube Music was only added in October? I took the ride in September.
It is still standard advice today, as far as I know. Tires are better, stability control is better, but all else being equal you are still much more dynamically stable and have a lot more friction with the road when the car is stopping in a straight line than when swerving.
Also, in the case of someone running a stop sign, it is far from a sure bet they are going to hit their brakes at all, so by swerving you increase the odds that you will still hit them, but now it will be while you have exhausted all your adhesion on lateral control. So now instead of a front end collision with all the benefits of airbags and crumple zones, you are at a significant risk of rolling the car or spinning off the road and hitting something immovable with a part of your car lacking crumple zones.
True if we all drove unicycles - but in the real world, tyre wear is uneven, brake wear is uneven, loading is uneven, the surface is uneven, and those differential forces are what modern ABS seeks to control.
The key difference between braking and accelerating is that in the former case, independent, potentially differentially worn brakes, apply force unevenly, making the chance of a loss of traction on one or more wheels higher. With acceleration, that force is applied through a differential, meaning it will be far more likely to be appropriately distributed.
If you want to decelerate while swerving it can be done, but it should be done through engine braking - and the tricky bit there is matching revs as you drop the clutch back in, otherwise you have too much retarding force and overcome the coefficient of friction, resulting in a skid.
Easier for those of us who grew up with double de-clutching and no synchromeshes, but when youâre in a critical situation, itâs still an awful lot easier to apply acceleration.
Absolutely. I was recently driving on a motorway in Portugal when a boulder (giant chunk of granite, 10+ tonnes) fell off the back of a truck - right in front of us, in a heavily laden (7 pax and luggage) car. Immediate massive cloud of dust, I checked my blind spot, veered across two lanes, and continued our journey, unscathed. I looked in the rear view, to see the car behind us jump on the brakes instead of evading. They caught the boulder.
Nobody killed, according to the news, but several taken to hospital in critical condition.
Oh, I say unscathed but our tyre exploded the next day, as apparently we caught a fragment, and again, thatâs not a âslam on the brakesâ moment, but rather âtrundle to a stop on the shoulder and walk to the conveniently nearby tyre shopâ.
In theory, it depends. In practice, slamming on your brakes is the correct call 99% of the time. To a large extent that is because of the "competent driver" part. I'd expect 80%+ of drivers to consider themselves just that, whereas the truth is of course the opposite.
So, the correct advice is to say "brake, don't swerve", so that drivers internalize that their first thought and reaction in any emergency should be to brake. Teach them to actually brakeâfully press on the pedalâwhile you're at it.
A slightly more nuanced advice would be "brake first, swerve as needed as a follow-up".
But I would never in good conscience be able to give anyone advice to swerve instead of braking.
It wasn't possible to stop at the speed the Waymo was moving at.
The Waymo didn't have the stop sign, the other driver did, at a three way intersection.
The other driver decided to suddenly enter the intersection, when the Waymo was like 5-10 meters away. This was after having stopped at the stop sign.
Either they weren't looking or intentionally trying to cause an accident. Swerving prevented the Waymo from crashing at 40 km/h into the driver's door.
> swerving is more likely to make you lose control
Even if you're not a panicky human but a optimally regulated control system?

I'd like to introduce you to what autonomous cars were already able to do in 2018: https://www.youtube.com/watch?v=khX0UCqcR3M
Thankfully they've now shipped their own product, YouTube Music.
And Google Pay, imagine my surprise back in 2021 when I signed up for Waymo and realized I had to manually type in my credit card. No Google Pay??? C'mon y'all, you're Alphabet!

Do you drive a lot? I feel like humans take evasive actions like this all the time.
Yeah I have done similar evasive maneuvers a bunch of times. Also people run stop signs constantly, a competent defensively driving human may have just not started driving forward yet when they saw the other car driving towards the stop sign with some speed. Iâm not sure of the exact timing in the story but Iâve waited at a stop sign when I saw another car driving towards the intersection many, many times, and a small percent of the time they donât stop.
Which isnât to say that the average driver wouldnât have hit it, itâs just not obviously superhuman.
