I think certain plastics could be safer material since you won't need to paint them to mark lanes. You'd just bake in the colors while extruding. The only problem I see is can plastics maintain the required texture to ensure the best grip for all kinds of tires and conditions. I would like them to test this out before using it even as a replacement for sidewalks.
