Self-driving cars can still be fooled by tampered-with signs

Researchers from UC Irvine and Drexel University studied methods to deceive self-driving cars' traffic sign recognition systems. They discovered that inexpensive stickers on signs can effectively confuse these systems. The study found that commercial vehicles' "spatial memorization" feature, which remembers sign locations, reduced the effectiveness of some attacks. However, creating fake signs proved easier than expected. The team tested five automated car models to enhance self-driving technology's safety and security.
