Depends on the country I suppose. In Romania doing 150 km/h in a 50 km/h area is pretty common, and generally speaking reckless driving, road rage and a handful of other things where cameras would help. Oh, and the government made it to phone recorded incidents are not acceptable proof in court, unless the recording device is government licensed (needless to say the licensing process is not clear). In countries where people drive responsibly generally speaking, cameras might only marginally improve things, but in Romania it would mean a reduction in the thousands of preventable deaths happening each year.
