Chris Gerdes (Stanford) on Technology, Policy and Vehicle Safety - MIT Self-Driving Cars

Stanford's Chris Gerdes on building autonomous race cars and shaping the first US federal self-driving vehicle safety policy.

The guest

Chris Gerdes — Stanford professor of autonomous vehicles and former first Chief Innovation Officer at the US Department of Transportation, where he helped write the first federal automated vehicle policy.

The gist

Chris Gerdes gives an MIT lecture bridging the engineering and policy sides of self-driving cars. He describes Stanford's autonomous race cars Shelley and the DeLorean Marty, which push tires to their physical limits to learn safety-critical maneuvers. He then explains the US system of manufacturer self-certification, the slow rulemaking process, and the 2016 federal automated vehicle policy with its 15-point voluntary safety assessment. He reframes vehicle ethics away from trolley-problem morality toward engineering risk reduction, and argues for anonymized data sharing modeled on aviation's ASIAS system. A long Q&A covers liability, passive-safety rollback, global coordination, and open-source cars.

Big reveals

  • Stanford's autonomous Audi 'Shelley' can lap Thunderhill at up to 120 mph and now exceeds every human on the development team.
  • Shelley is within about one second of IndyCar driver Junior Hildebrandt's pace on a 1:25 lap.
  • A Volpe report found almost nothing in current federal motor vehicle safety standards prevents putting an automated vehicle on the road.
  • NHTSA interpreted that references to 'driver' in the safety standards can refer to the self-driving AI system.
  • The September 2016 federal automated vehicle policy uses voluntary guidance and a 15-point safety assessment rather than binding standards.
  • Gerdes argues the trolley-car dilemma is not an impossible problem; engineers should solve it through risk reduction, not moral ranking.
  • Human error is the primary factor in 94 percent of accidents, so merely imitating humans leaves safety potential on the table.

Things worth remembering

  • Gerdes recorded the lecture during his first week back in a civilian role after wrapping up at USDOT.
  • Racing maxim cited: 'if you want to finish first you have to finish' — be fast but accident-free.
  • Shelley drove up Pikes Peak and on the Bonneville Salt Flats and appeared in an Audi commercial with Zachary Quinto and Leonard Nimoy.
  • Aviation requires pre-market certification before aircraft can be sold, but US cars rely on manufacturer self-certification.
  • Making a new federal vehicle safety standard takes a minimum of two years and realistically about seven.
  • The DeLorean 'Marty' was electrified with a Renova Motors drivetrain and programmed to perform precise autonomous drifts and donuts.
  • Aviation's ASIAS data-sharing system grew from 4 to 40 airlines using anonymized safety data through MITRE.
  • Gerdes joined USDOT after an unexpected call from the White House; the policy went from a one-page outline in February to launch in September.
