Researchers were able to trick a Tesla Inc vehicle into speeding by putting a strip of electrical tape over a speed limit sign, spotlighting the kinds of potential vulnerabilities facing automated driving systems.
Technicians at McAfee Inc placed the piece of tape horizontally across the middle of the "3” on a 35 mile-per-hour (56kph) speed limit sign. The change caused the vehicle to read the limit as 85 miles per hour (136.8kph), and its cruise control system automatically accelerated, according to research released by McAfee on Feb 19.
