I'm guessing you won't do what we saw in Queensland, Australia when we spent time there. Folks from the bush would make a metal frame covered with metal hardware cloth that you could see through. It was attached to the front fenders via hinges. When they were in town, they would fold it down onto the hood (bonnet?). When they raced home over gravel roads (they always raced!), they would raise the protection over the windshield (windscreen?). It also kept kangaroos out of the front seat, a very dangerous situation.
