What is your speeding threshold? For me, I try to stay at or within my threshold; however, sometimes I can't help but to exceed it. For example, today I was traveling at my threshold of (5 over city) and three perfectly good rabbits passed me. first was going 15 over, the other two were going 12 over. I followed suit of the 12 over. We were on a 3 lane highway pretty much.
City: 5-7 over
Highway: 10-15 over.
Last question: Do your countermeasures affect your threshold? How much?
