Should we say that he considered the speed limit more a guideline than a fixed amount? The first thing the police officer did was pull out the ASD and make him blow into it. He blew zero at that stage, but he was pulled over and that's the way they handle it. We are not the experts on what kind of effect that would have. There's certainly a deterrent effect for people who are afraid they might get caught. But presumably you're going to catch more people and that would result in more trials.
On the other side, we have, particularly through the restrictions on evidence to the contrary, taken some steps to simplify trials and reduce the amount of time that might be involved in the courts in proving the case. If we're talking simplification, then that would be the kind of thing we would be hoping as a package would make things a lot easier for the police to enforce the law and for the prosecution of the law.
