Red cars seem to attract more than just the eyes of the law. Something about a red car says, "Hey! Look at me!" It's a blood color, too, which has been shown to increase road rage in some people. Go figure.
Hummers are big, expensive, and bold, and really don't look like they belong on the road. I wonder if cops feel challenged by them? Like, "Yeah? And WHO do you think YOU are, huh?" Jags say $$$, and maybe are less a target because lawyers run with $$$. Odd, as Hummers ain't cheap, either.
I had to go and look at a Scion. The brand died a few years ago and the cars were rebranded as Toyotas. Some models were okay, a couple can nicely be called 'ugly'. The FR-S is even kind of classy looking. I can see why a cop might chase that one!
