I mean, I can think of many ideal places for such things. Intersections for instance, where cars will be wanting to slow down or come to a stop regardless. Speed limit changes, where you want cars to slow down. Even in place of speed bumps, assuming you can get enough of a drag on the car to effect a slow down.
Now that’s an interesting idea; basically external regenerative braking. Not too helpful on a highway, but I suppose it would be useful in the situations you described.
