How do you persuade a skeptical public that your autonomous automobiles will not be solely safer than human drivers but in addition a greater option to get round? If you’re Waymo, the reply is knowledge — and many it.
The Alphabet-owned firm revealed a brand new security hub right now, full with shiny graphics and a large number of charts that can be periodically up to date, with the overarching message that its autonomous automobiles 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 tougher take a look at the entire autonomous car trade — together with Waymo.
“This issues quite a bit to us”
“This issues quite a bit to us,” stated Trent Victor, director of security analysis and greatest practices at Waymo, “to be trusted.”
To be certain, self-driving vehicles have a picture drawback. They stumble into building zones, block ambulances, run purple lights, and even injure the occasional bicyclist or pedestrian. Numerous public opinion polls have proven declining assist for autonomous automobiles through the years and an increase in outright hostility towards the know-how.
Waymo thinks its new strategy to transparency might help flip the tide in its favor. The hub incorporates a whole lot of new, beforehand unreported data, together with the variety of driverless miles Waymo has racked up in every of the 4 cities through which 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 knowledge, 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 firm says it has round 300 automobiles working every in San Francisco and Phoenix, its two most important markets.
In looking for one of the simplest ways to speak its security message, Waymo zeroed in on a system that compares its driverless automobiles to human driver benchmarks in crashes that trigger accidents and crashes that end in police studies. Last yr, Waymo decided that its automobiles had been 6.7 occasions much less probably than human drivers to be concerned in a crash leading to an damage, 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 firm is barely presenting this knowledge for Phoenix and San Francisco, the 2 cities the place it has essentially 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.
Another part of beforehand unreported knowledge is the proportion of Waymo’s crashes which can be extraordinarily low velocity. The National Highway Traffic Safety Administration requires autonomous car operators to report all crashes and collisions, no matter severity. For Waymo, which means reporting a whole lot of extraordinarily minor bumps and scraps, which the corporate thinks can skew the general public’s notion of its automobiles. There is now a big repository of crashes involving self-driving vehicles, however a lot of it lacks essential context.

The firm determined to carry extra nuance to the federal government’s knowledge by together with a bit 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 consists of crashes solely in Phoenix and San Francisco.
“One mile per hour Delta-V is sort of a very insignificant crash,” stated Kristofer Kusano, employees security researcher at Waymo. “So that is normally so minor of a crash that it’s not truly even shifting the car a lot.”
This all seems to be fairly good for Waymo, which is clearly the last word aim. But the corporate is aware of that it wants unbiased teams to confirm this knowledge — 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 stated. “I really feel privileged to have the chance to publish.”
With the introduction of this new security hub, Waymo can be making its methodologies accessible for obtain, so extra exterior researchers can take a look at the uncooked numbers. “[We’re] permitting individuals to duplicate the outcomes,” Victor added. “See what we did, prolong it, take a look at it by way of new lenses, add extra complexity, and simply advance the science.”
