Brian Douglas introduces Braitenberg vehicles, simple robots whose sensors are wired directly to motors yet show surprisingly lifelike behavior. He draws on Valentino Braitenberg's book Vehicles.

Mark Rober tests whether self-driving cars can be fooled, comparing a lidar-equipped car with a camera-only Tesla in scenarios including a painted Wile E. Coyote wall and smoke.

A clip from Tesla Autonomy Day 2019 where Elon Musk argues cameras are enough for self-driving and calls lidar a fool's errand.

Andrej Karpathy's CVPR 2021 presentation on Tesla's Autopilot, covering its vision-based approach, sensor choices and the scale of Tesla's deep learning compute cluster. This upload is a lower-quality copy of the talk.

A hands-on comparison of self-parking systems on a Tesla Model S and 3 (including AP1 vs AP2), an Audi e-tron GT, a Ford Mustang Mach-E and a BMW i4 M50. It tests both parallel and perpendicular parking and finds Tesla's newer vision-based parking noticeably weaker than the others.
