It’s called the Intelligent Speed Limiter, a system in Ford’s new S-MAX with the ability to read traffic signs, keeping you under the speed limit and in the clear of getting a speeding ticket. The Intelligent Speed Limiter allows you to set a maximum speed which is automatically adjusted by the Traffic Sign Recognition system. Here’s how it works: there’s a camera mounted on the windshield that scans road signs and restrictions, reducing the vehicle’s speed to match.
