I used to brake early, then kinda coast to the end, then stop at the end, but that deceleration at the end caused the system's alarm to go off. So I had to drive faster with more constant deceleration when approaching a light. Pain in the ass. I was also driving in Providence at the time, and drivers there are the scariest I've seen. I frequently had to perform emergency maneuvers to avoid cars that suddenly pull out or stop in the middle of the road to let someone out. Anyways, we didn't get much discount, and had to drive with extreme care, and still had those annoying-ass beeps. But in your case, 20 miles/week it's probably a good idea to get it.
