    Why Waiting for Perfect Autonomous Vehicles May Cost Lives

    Some people think autonomous vehicles must be flawless before humans take their hands off the wheel. But putting AVs on the road before they're perfect improves the technology more quickly—and could save hundreds of thousands of lives over time.

    Deploying Autonomous Vehicles Before They're Perfect Will Save More Lives

    Autonomous vehicles should only have to be moderately better than human drivers before being widely used in the United States. This approach could save thousands of lives annually even before the technology is perfected.

    Model of Automated Vehicle Safety (MAVS)

    The safety of autonomous vehicles is a principal concern for the transportation industry, policymakers, and the public. Comparing the impact on road fatalities under many different scenarios can help understand the circumstances in which autonomous vehicles can provide the greatest safety benefit.

    How Safe Should Autonomous Vehicles Be Before They're Introduced to Market?

    RAND researchers Nidhi Kalra and David G. Groves developed a model to compare 500 different scenarios of autonomous vehicle introduction, adoption, and improvement. The research shows that putting autonomous vehicles on the road sooner, allowing them to improve quicker, could save hundreds of thousands of lives over time.

    New York Terror Attack: Can Vehicle Attacks Be Prevented?

    The recent vehicle attack in Manhattan was the deadliest terror attack on New York since 9/11. Preventing every attack is unrealistic, but with increased vigilance, cooperation with law enforcement, and intelligence sharing, citizens can help mitigate the threat of terrorism.
