I dunno, knowing the exact relative velocity of the car in front of you seems like it could be useful and is something humans can’t do very well.

I’ve always wanted a car that shows my speed and the relative speed (+/-) of the car in front of me. My car’s cruise control can maintain a set distance so obviously it’s capable of it but it doesn’t show it.

If your car is maintaining speed of the car in front then the car in front is going speed that is showing on your speedometer.

Yes, that’s true, but I don’t see how that relates to my comment at all.

I said the relative speed. If the car is going the same speed as me then the relative speed is 0mph. I want to see that when I’m not using cruise control.
