Well, what they just put in there is nothing new in cars. It's not actively reporting you to the police. you aren't getting a ticket in the mail, however it is likely keeping a record of it and if authorities wanted to attain that info, I'm sure they could with a warrant, or if you were involved in an accident or something. If Insurance companies wanted it, they could request it too, but some Insurance companies have gone to putting devices in peoples cars and adjusting rates based on driving habits. But cars are not reporting to the feds...Yet. That's coming though, i'm sure.
What they just explained was basically Adaptive Cruise Control. I have a Hyundai Sonata and it has it. It's my Second Sonata since 2016 and my 2016 version had it as well. I actually love it. Makes long trips so much easier, not having to adjust or turn off CC whenever you approach somebody going slower or a cluster of cars on the interstate. it adapts you to the speed of the person in front of you and you can wait for a clearing to pass without having to manually adjust down or brake or turn off CC altogether, one you get back in the open it goes back to the set speed. I can adjust the safe distance or how close I get to the car in front. My car uses the navigation system to know the speed limit or type of road you're on for the lane assist purposes.
So No, Ford isn't telling the Cops to send you a speeding ticket whenever you cross a threshold. But I can see a future where the Feds make car manufacturers govern the speed on cars to where you can't speed.
