Camera's can't see in the dark. There is no perfect sensor. Waymo relies multiple sensor modalities: Cameras, Lidar, ultrasonics, radar, gps, inertial measurement units.

Also microphones. Don’t forget the (external) microphone sensors.
Cars don't drive in the dark. Roads are usually lit. And every car has its own lights for seeing where you are driving.

Not always. Definitely not all freeways.

Not always far enough. Especially at freeway speeds on unlit freeways.
So how can humans do it?
If humans don't have lidar but can drive it's an existence proof of the viability of that approach.

Interstate highways and local roads are generally unlit outside of urban areas. But in fairness, Waymos don't operate in those places anyway.
