Re: "... idiots in Range Rovers who think they're indestructible."
I had a friend who used to drive Land Rovers in Africa.
They weren't indestructible, and there were many crashes involving wildlife out there. So people fitted bull bars to theirs, thinking it would make them survive the crashes better.
My friend was one of the few who didn't. When he was involved in a crash with wildlife, he found that parts were plentiful to fix the damage... from all the others with major chassis damage due to the mounting of bull bars!
