There are several initiatives to tag evidence to plates and locations so that people can watch out for bad and dangerous drivers.
There is no stigma to speeding. Nobody thinks it reflects badly on you.
People would scream if the government started circulating lists to traffic cops of cars that should be watched for speeding, but that's really not an issue of "being labeled a speeder" so much as "being singled out for harassment by the government".
Where on earth do you get this generalization from? In my circle of associates, speeders are near-universally castigated as people who willfully endanger the safety of innocent people. And I wouldn't think that would be surprising when you take into account the fact that many/most friends and loved ones have to drive frequently, and the fact that car accidents are so common in the domain of stupid pointless horrible accidental deaths.
Unless you're referring to people who are just going 5-10 mph over, which most people wouldn't call "speeding" conversationally.
