An article for you Dr Bill. http://www.motherjones.com/news_wire/bullbars.html
I particularly liked the quote:
"Nonetheless, in North America, the potential danger posed by bull bars has so far drawn little attention. Part of the reason is that the US and Canada have fewer pedestrians than the UK."

I see what they are saying but I had the strange idea that we were all pedestrians at some point, they obviously have invented total drive to the door shopping and working in the USA .. no, on second thoughts maybe they have .. next research - obesity and exercise?
