Mark Rober tested out both a Lexus equipped with lidar, and a Tesla that uses just visible light cameras. He wants to see if which of the systems will fall for a variety of tests that could fool self-driving cars. Including painting a fake road on a brick wall.

Bonus points, he took a lidar onto his ride of various Disneyland rides. He tries to see if by just bringing his lidar on Space Mountain if he could map and 3D print it. Results of that at 16:25
