Every one has seen these commercial trucks that carry sheet glass on the sides. What concerns me is the close proximity of these protuding racks edges to our legs if they get too close for comfort. For example, you stop your bike at a red signal light and you are looking to see that no one is going to plow in to the back of your bike. There is a car to your front; the left side has a oversized SUV ,a big 350 series truck or a vehicle that has pullled in to close with no room to manouver between in case the car in the back decides not to stop in time. On the right is a glass truck with it's protuding edges. Yea I know the right thing to do is give your self plenty of space up front. But these trucks look and are intimidating to me with their sharp protuding angles.
