Lidar-based. Here it is:
To construct this interactive graphic story and simulate the challenges the industry faces developing autonomous cars, The Washington Post reviewed voluntary reports from AutoX, GM Cruise, Nvidia, Uber, Waymo, Nuro and other self-driving vehicle companies that describe their autonomous technology and safety standards; autonomous car research from the Congressional Research Service and the University of Michigan's Transportation Research Institute; and video lectures on self-driving technology.
The Post also reviewed more than a thousand pages of autonomous vehicle disengagement reports, filed to the California Department of Motor Vehicles from 2015 to 2018, as well as crash reports involving self-driving cars from the National Transportation Safety Board and guidelines on automated vehicles from the Transportation Department.
The Post interviewed individuals from autonomous vehicles companies, academics and other experts in the industry. The Post also participated in self-driving car tests in Chandler, Ariz., and San Jose, Calif. Transportation Secretary Elaine Chao’s estimate on the number of autonomous vehicles in the United States came from her speech at an Uber Elevate Summit event earlier this year.
While autonomous vehicle makes and models, and the level of technological advancement, vary by company, the 3-D model of the car depicted in this graphic is based on a generic, four-door compact minivan and doesn’t represent a specific company’s vehicle. The representation comparing sensor capabilities with human vision is based on research from the University of Michigan’s Transportation Research Institute. The 3-D world doesn’t represent an exact location within the world. However, a one-way street to the airport — one that is unhindered by traffic jams, broken-down kangaroo trucks and other inconveniences — would be nice.
