No SR20 (and the wrong Z), but I spotted a gray post-refresh 370Z with something dangling off its rear bumper, which apparently means they want to race. I didn't get a good look at it due to highway traffic - it wasn't a doll, but it was a red, rectangular object about 2-3 inches tall.

For some reason, I really want to know what exactly it was. The driver certainly didn't intend to race.
