Hundreds of motorcycle riders every year are injured or even killed by the neglect and irresponsibility of people throwing their grass clippings in our roads. When you hit their clippings on a motorcycle it's like hitting ice, causing the rear wheel to come out from underneath you and thus causing the bike to lay down.This  also allows our catch basins to stay clean, when grass goes in our streets and it rains it has potential to clog up those basins and cause flooding
