On a related topic, Jan 1 2018 Illinois gets revised laws for bicycles. Allowed to use shoulder (if clean enough but not marked as bike lane as currently required). Cars allow to pass in no passing zone if bicycle is doing less than half of the speed limit, they give 3 feet clearance, and don't exceed the speed limit. Lets see how they work then try to spread them to other states. http://www.illinoisbicyclelaw.com/20...bike-laws.html (good bicycle accident lawyer for chicago).
