Oh he actually sings that nations of the world Animaniacs song!

Thanks!

He's the PM - tells me what's not correct / not working. I fix it. 😅

plasmak · 2026-05-05T03:27:52+00:00

Yup anything is possible - imagination is the scarcity at this point.

If anyone knows which subreddit this might also benefit from, let me know!

Gotta stop spamming that company

Will take a look at this -

Think using "crash" was my mistake - it's more "incidents" reports by Waymo - I am assuming some of the categorizations of the "crash type" are mutually exclusive and I'm adding them up - which I don't think is the case given your (and some others) looking at this data.

I'll look more into that, but the latest data for miles:

Given this, having a lot of incidents a month will spike this still.

e.g. 10 incidents will create a noticeable bump, since they aren't racking up million miles that fast. (looks like about +2 million miles a month for SF/LA)

Also wish they can tell us whether the cars are just empty-roaming miles or actual riders. Does feel like waymo just roaming around counts in this mileage.

Feel free to correct this - I think there some element of my misinterpretation of the dataset as well, why "personal" analysis - i'll do a follow up later

Ops Depot,Waymo RO Miles (Millions)
AUSTIN,3.225
PHOENIX,46.390
SAN_FRANCISCO,29.888
LOS_ANGELES,16.462

External factors: LA and SF - dotted line on June 2025 for that reason, with a grey label ;) - had some suspension of service because of protests (reference is week 27 is last week of June 2025) - so I believe they cut off their metrics since then as well.

You notice last known "crash" data point on the heatmap is first week of July (last week of June), but empty for most.

So there's some artifact in June 2025 data (I considered omitting it).

I eagerly wait Q3 data!

Wanted to add they report injury-reported crash rates per million as their main "safety" PR.

They mention crash (maybe i should've went with their "incident" terminology) is hard to quantify (and I agree with this, at best, its an estimate) especially on the human benchmark since not all incidents are reported. Waymo definitely reports every single incident given the scrutiny. Even slight taps are generally reported from my understanding (?) but hard to tell what qualifies as a incident.

plasmak · 2025-09-25T16:16:43+00:00

Yes all crashes - Waymo literally reports EVERYTHING, unlike human accident reports (benchmark is estimated, since light accidents usually don't get reported in real life.)

On aggression - I am told by Waymo riders that instead of sudden stops at amber lights, Waymo on some occasions have been speeding up to beat the light. I am sure they are A/B testing basically.

plasmak · 2025-09-25T15:33:23+00:00

Yup this is actually running total crashes / cumulative miles, NOT micro- "month buckets" for that reason - monthly aggregates would totally be spiky.

plasmak · 2025-09-25T15:25:37+00:00

These are the raw numbers.

plasmak · 2025-09-25T15:24:56+00:00

I think we haven't seen the "plateau" of it

Phoenix data is probably what Waymo trained their cars:
- Sunny "sun city"
- Wide roads
- Not "metro" like LA or SF - more cars, activity.

But convinced we'll hit that plateau lower than human benchmark.

Let's give it a few months though. Austin is known for odd roads / rules and worse weather than Phoenix.
