How do you persuade a skeptical public that your autonomous autos will not be solely safer than human drivers but additionally a greater solution to get round? In case you’re Waymo, the reply is information — and many it.
The Alphabet-owned firm revealed a brand new security hub as we speak, full with shiny graphics and a mess of charts that will likely be periodically up to date, with the overarching message that its autonomous autos are to not be feared. The transfer comes as Waymo seeks to develop its footprint, win over new prospects, and cement its lead within the race to deploy extra driverless vehicles. It additionally comes as security regulators have begun to take a more durable take a look at the entire autonomous automobile trade — together with Waymo.
“This issues rather a lot to us”
“This issues rather a lot to us,” mentioned Trent Victor, director of security analysis and greatest practices at Waymo, “to be trusted.”
To make sure, self-driving vehicles have a picture downside. They stumble into building zones, block ambulances, run purple lights, and even injure the occasional bicyclist or pedestrian. Quite a few public opinion polls have proven declining assist for autonomous autos over time and an increase in outright hostility towards the expertise.
Waymo thinks its new strategy to transparency may also help flip the tide in its favor. The hub accommodates quite a lot of new, beforehand unreported data, together with the variety of driverless miles Waymo has racked up in every of the 4 cities wherein it operates (or, as the corporate calls it, “RO miles” for “rider-only miles”). As of June 2024, Waymo has pushed 15.4 million miles in Phoenix, 5.9 million miles in San Francisco, 855,000 miles in Los Angeles, and 14,000 in Austin.
The final time Waymo launched its security information, in December 2023, the corporate had solely pushed 7.1 million rider-only miles. Now, it has over 22.2 million miles throughout 4 cities — which displays a 212 % improve over eight months. The corporate says it has round 300 autos working every in San Francisco and Phoenix, its two principal markets.
In trying to find one of the best ways to speak its security message, Waymo zeroed in on a formulation that compares its driverless autos to human driver benchmarks in crashes that trigger accidents and crashes that lead to police stories. Final yr, Waymo decided that its autos had been 6.7 occasions much less possible than human drivers to be concerned in a crash leading to an harm, or an 85 % discount, and a pair of.3 occasions much less prone to be in a police-reported crash, or a 57 % discount. The corporate is barely presenting this information for Phoenix and San Francisco, the 2 cities the place it has probably the most miles traveled.
Now, it’s making use of these formulation to a bigger set of knowledge — and the numbers nonetheless look fairly good. As of June 2024, Waymo’s robotaxis have 73 % fewer injury-causing crashes as in comparison with human benchmarks and 48 % fewer police-reported collisions. It additionally added a brand new class: airbag deployment crashes. Waymo says it has 26 fewer airbag deployments than the human benchmark, or a lower of 84 %. It additionally breaks out every of those figures for Phoenix and San Francisco particularly.
One other part of beforehand unreported information is the proportion of Waymo’s crashes which are extraordinarily low pace. The Nationwide Freeway Visitors Security Administration requires autonomous automobile operators to report all crashes and collisions, no matter severity. For Waymo, which means reporting quite a lot of extraordinarily minor bumps and scraps, which the corporate thinks can skew the general public’s notion of its autos. There’s now a big repository of crashes involving self-driving vehicles, however a lot of it lacks essential context.

The corporate determined to carry extra nuance to the federal government’s information by together with a piece in its security hub that highlights the % of collisions with a Delta-V — a metric used to measure the change in velocity throughout a collision — that’s lower than 1mph. Waymo discovered that 43 % of the crashes disclosed to NHTSA had a Delta-V of lower than 1mph. This contains crashes solely in Phoenix and San Francisco.
“One mile per hour Delta-V is sort of a very insignificant crash,” mentioned Kristofer Kusano, workers security researcher at Waymo. “So that is normally so minor of a crash that it’s not truly even transferring the automobile a lot.”
This all seems to be fairly good for Waymo, which is clearly the last word purpose. However the firm is aware of that it wants unbiased teams to confirm this information — and replicate it — if it’s ever going to realize mainstream acceptance. To that finish, Waymo has produced dozens of analysis papers outlining its security strategy and has submitted lots of them to peer-reviewed journals for publication — a number of of which have already been accepted.
“We’re actually enthusiastic about that,” Victor mentioned. “I really feel privileged to have the chance to publish.”
With the introduction of this new security hub, Waymo can be making its methodologies obtainable for obtain, so extra outdoors researchers can take a look at the uncooked numbers. “[We’re] permitting folks to copy the outcomes,” Victor added. “See what we did, lengthen it, take a look at it by way of new lenses, add extra complexity, and simply advance the science.”
