Hmm. I'm always crusading for people to slow down and stop being in such a frantic hurry all the damn time. In Utah, people go 85 in school zones (in fact 125 in some cases) and kids are being killed every day because of it.
Is 10 mph over the speed limit too much speed? I don't know, but I know that too many people drive as IF they were having a life-threatening medical emergency rather than following safe speed limits. If the weather is good and the road is clear, it's fine to go a few miles an hour over the speed limit.
But, speed limits aren't there just to make your life inconvenient. There's a reason they deem some zones safer for going faster than others, usually because of residential areas having lots of kids around, etc. Speed limits aren't just arbitrary.
In some places where drivers are not usually exceeding the speed limit I can see where this could be a nuisance. But in Utah, where almost nobody drives at a sane speed, and people go WAY over what could be called acceptable levels of speed, nothing else has worked to slow drivers down. So, this seems like it could be a real step in the right direction.
If people WON'T do the right thing, should we FORCE them to, especially if it saves lives? That's the question.
