Is there any move towards building dedicated animal crossing bridges? These have been proving very successful where deployed in the US.
Also, I'm pretty sure they like hanging out on the road, because the road traps heat and stays warmer at night.
The same way they got wolves, deer, oppossums, raccoons, coyotes, dogs, elk, and more to do it? They’re mainly underground tunnels or overpasses that are covered in natural materials, free of scary, fast, roaring machines, etc
You would have to put up extremely tall barriers along all the roads, which is an expense I think most people would be unwilling to fund.
Often they seem to just be standing around on the road until I light them up with my headlights and they start moving.
