It's hard to tell without doing a census-style count because it's human nature to recognize and remember the familiar items in a large group.
Years ago, my best friend bought a Saturn and commented numerous times in the following months on how many Saturns he saw on the road.
A decade later, he bought a Mazda and, once again, commented numerous times in the following months on how many Mazdas he saw on the road.

There may be a similar skewing of people's perspective on this topic.
