Any idea that could be a solution for roadkills deserve to be explored at least. Think in the millions of terrestrial animals, some endangered, that we could save each year.

Would be a real blessing for vanishing amphibians, hedgehogs, snakes, endemic terrestrial crabs, big cats... On the other part could be a problem for birds, bats and flying insects also, of course. And will boost the feral cat problem.

For good or worse, from a environmental point of view would be a real game changer.
