Adding 5 minutes to my regular commute time and avoiding big fines and tickets is more worth it to me than doing over the limit and having to slow down every time I see a police patrol car on the highway.

My regular commute time was 55 minutes doing speeds 70mph+. Now it is 1hr doing speeds 60mph+ (Sometimes I can get up to 85 miles per hour depending on the slopes of the road). I definitely am positive that now I won't get a speeding ticket and I don't have to slow down when I see highway patrol cars.

I don't consider that driving like an old blue haired lady. I consider it as driving wisely (I'm only 23 btw and I used to drive crazy up until 1 month ago doing speeds as high as 120mph).
