Cities that build protected lanes for cyclists end up with safer roads for people on bikes and people in cars and on foot, a new study of 12 large metropolises revealed Wednesday.
While they would be better, sometimes it is a lot more approachable to start small and cheap to get people to understand the benefits. It is also sometimes better to do something temporary when you know it might need adjustments to finalize the layout into something more permanent.
They're not there temporarily because they're cheap; they're there permanently because car-brained traffic engineers are still addicted to breakaway design.
