Murray, I guess it comes from being this big melting pot and having no traditions older than 300 years....and the thing is, only a small % put those things on their cars....and many fewer in some areas of the country. But it only takes 1% of millions to hit you every day....Americans simply do not have the 'traditional' reserve we associate with the English...(I'll bet in Finland they use VERY few bumper stickers!...I wonder about Japan...
