Obviously you don’t drive on the national Highways! When have you ever seen anybody drive the speed limit, keep a safe distance etc. Dropping the speed limit will cause a surge in deaths because you will have the slow pokes driving at 55 and the rest driving at 75 or 85 miles an hour. I don’t like needless laws that say they are trying to protect me. I don’t like seat belt laws, helmet laws. This is not the job of government! We have so many laws now you can’t hardly turn around without breaking some law somewhere!
You’ve never encountered a slowing of traffic on the national highways? Wow. You’ve been lucky, and sheltered!
