What do you mean by obstructed? You are going to cover the sensor housing with something or you mean there is some small wall in the way?!?

Stop and go ACC on most vehicles uses a combination of forward facing radars and a forward facing camera, i.e. a sensor fusion algorithm. The radars don't work well once the vehicle comes to a stop (or at low speed) and is where the camera works best. The camera is usually mounted in the rear-view mirror housing. I think it's also used for the auto-high beam.
