Laying a trap for self-driving cars

Will self-driving cars be able to prove they are not a robot?
It might be necessary:

self-driving cars can be hacked by just putting stickers on street signs

According to the researchers, image recognition system used by most autonomous cars fails to read road sign boards if they are altered by placing stickers or posters over part or the whole road sign board.

The paper:

Robust Physical-World Attacks on Machine Learning Models
(Ivan Evtimov, Kevin Eykholt, Parlance Fernandes, Tadayoshi Kohno, Bo Li, Atul Prakash, Amir Ramait, Dawn Song)

We physically realized and evaluated two attacks, one that causes a Stop sign to be misclassified as a Speed Limit sign in 100% of the testing conditions, and one that causes a Right Turn sign to be misclassified as either a Stop or Added Lane sign in 100% of the testing conditions.
