Commuting- Do police set up speed traps during rush hour in your town ?

[cbelt3]

Driving my son to school the last couple of days (Missed da bus... :banghead: ) I've noted a little town along the interstate that has speed traps set up during peak rush hour.

I've always found that to be a really BAD idea... heavy flowing traffic and people suddenly slam on their brakes because they see a cop. Gotta be creating more accidents than it 'calms' traffic. In fact I saw one accident just before a speed trap location, possibly caused by that factor.

Experience and Opinions ?
