I am not aware of any vehicle with autonomous capabilities which bases it's operation on "following other cars".

A number of cars including the Infiniti Q50 have a variation of the "follow the car in front of me", I used it the other day on the highway it is more about cruise, but combined with the stay in lane feature that it also has it might quality for what you are looking for.

The Tesla Model S, X and imminent 3 use this heuristic.

The autopilot will look for lane markings or road surface edges, but seems to favour following the vehicle in front where possible. This especially helps drive better in rainy weather where road markings are obscured by reflections.

Wow...that's like literally "If all your friends jumped off a cliff..." If you had a line of self driving cars, and one mistakenly heads for a ledge in a bad rain storm, there is the potential many of the following cards could do the same as well.

Not exactly. I've followed a car in front in fog where I couldn't really see where I was going and I figured if there was a wall or cliff or something I'd see the car in front deal do odd stuff and hit my brakes.
