Frankfurt Car Show: Going tech crazy in drive for more sales

At the recent Frankfurt Car Show, Ford unveiled a new feature that lets drivers pre-set their car to go at or just above the speed limit. In-car cameras and software read and react to road signs, speeding the car up or slowing it down.

Active Speed Limiter is available on select models in Europe, but not, ironically, in the US, Ford’s home country, where road signs come in different shapes and sizes, and are often obscured by shrubbery.

So it goes on the road to the self-driving, or autonomous, car — a journey of, well, stops and starts that most experts say will take a couple decades to complete.
