ok, i've noticed several threads arguing about speeding, and several having a go at speed cameras.. Im wondering what you guys would personally do to stop people speeding. PLEASE dont turn this into a debate about whether we should speed or not.. just imagine you'd been appointed your local anti-speeding officer or whatever, and you had to come up with a way to stop people speeding on your roads (be it advertising, education, speedcameras, traffic calming, whatever).. then try and justify it (ie cost/benefit).. im just curious if we can actually come up with a better idea than speed cameras..
