Everybody is working on making robocars drive more safely and cause fewer accidents. Waymo recently released a paper outlining how they ran a large number of accidents in simulation, and tested what happens if the Waymo system is driving the primary car (which caused the accident) or the secondary car (which didn't) in 2-car collisions. No surprise that they prevented the accidents when being the primary car. More interesting is they prevented almost all the accidents when being the second car.

In other words, once you get a fleet of robocars out on the road, not only will they reduce accidents by not causing them, they will also prevent other people from causing accidents.

Read about it in my new Forbes site piece at Waymo study says cars would be good at avoiding accidents
