Snow removal equipment
I was in Maryland during the recent blizzard. I was able to make the return drive to Pittsburgh on Monday. The roads where clear, however road crews were doing snow removal on the shoulders, left and right. I found during my drive the crews were often on turns and had I had no warning to be able to change lanes for safe distance.
That's when I thought of a SNOW PLOW notification. It would include a left or right choice and on road or shoulder choice. Moving or stationary would be a choice too, but might be a bit much for while driving.
This feature would be great because people that live with snow can watch their route from a safe place, then start driving when they see a SNOW PLOW on their route.
