Wildlife straying onto the roads isn't such a big problem here on fair Albion. We've killed most of it.
In other parts of the world, however, it's a continuing threat. Such as in Norway, where a man recently swerved to avoid a moose.....and hit a bear.[link]
Y'see, city-folk: THIS is where you need bull-bars.
A little chickenwire over the windows wouldn't hurt, either.....
