There is a big difference between speeding and driving/riding recklessly. When the 55mph speed limit was the norm on the interstates, there were people(I was one of them) who had radar detectors and used CB radios and went 70mph. Now that the speed limit is 65/70mph people go 80mph. The increase in speed does not put peoples' lives in danger, but it is those drivers/riders who operate their vehicles without regard for others safety that should be ticketed....
+1 Running 10 mph over the limit on an open roadway is not inherently dangerous. Weaving in and out of traffic, texting, driving too slow, not paying attention..... are far worse. I don't feel safe at all unless I'm moving faster than the majority of traffic. I like to be in the fast lane moving at least 5 mph faster than most of the other traffic. If someone faster approaches me from the rear I gladly move over and let them by. Much safer than having to worry about what's in front of me and what may be overtaking me in all lanes. IMO
