As others have pointed out, your example doesn't hold water: other countries have speeding cameras already, and our speedometers are already sufficiently accurate.
"others" is one person who is being incredibly pedantic. Red light cameras or speeding cameras on a few areas !== all encompassing surveillance that implements 100% compliance with the laws.
If you guys are going to harp on speeding cameras existing as well to invalidate the argument, how do you handle the fact that they have been shown to increase accident rates and many communities have pushed to get rid of them as a result?
You're confusing red light cameras at intersections with speeding cameras. There has been no research showing that speeding cameras increase accident rates.
Do you have a better example?
