I think it is a matter of time...if you drive a lot you will probably get a ticket. Here in California where there are lots of drivers I notice the cops in distinct places waiting to nab a driver passing by. Some of these places are legit: near a school, near a residential area, etc. etc. So maybe you were passing through one of those zones.
Agree with the red car thing.
And I can't resist this....anyone see "Little Miss Sunshine"?
