First, the law in the OP is an American law.

Second, I find it difficult to believe that there are countries where driving slightly faster than a number printed on a road sign can result in prison time.

If I've made an error, it's because I drew a reasonable, albeit incorrect, conclusion; it isn't because I'm an ignorant American who doesn't consider the existence of other countries. If you had a correction, you should have posted it rather than a snide comment along these lines.
