Much as we'd like to emulate our NASCAR heroes, breaking the speed limit often comes at a price. Ford is hoping to prevent accidents and speeding tickets by introducing cars that can see what the speed limit is and preventing heavy-footed motorists from driving any faster. Ford's Intelligent Speed Limiter tech will first appear on the new Ford S-Max that's launching in Europe that could just change the way that we drive.
A camera mounted on the windshield scans the road signs on the sides of the highway and, when the vehicle enters a 20mph zone, the system reduces the top speed to match. Rather than controlling the speed with automatic braking, the car limits its own velocity by adjusting the amount of fuel being pushed to the engine.
