I started driving when there was no speed limit in Montana. On the edge of a town there would be a sign that said "end of speed zone". Thats what it meant too. I had a couple of hot rods and then a red 68 Camaro, no speeding tickets, then along came the federal 55 mph speed limit. The fine in Montana was $5 pay on the spot and didn't go on your record. At that time I had a 75 Trans Am with a built 455. Top end was 160mph. I got loads of tickets. I am sure over 50. But, I also got some others like, reckless driving, night time speeding, failure to drive in a careful and prudent manner. Basically, only went past 100mph twice a trip. Starting and stopping. I was living in Montana and working in N Dakota. Had a fleeing a police officer in ND. $500 fine in those days and no driving in ND. I had managed to out run them at night every other time. But, in the flats of central N Dakota a 2-3 mile lead on a Sheriff's Dodge with a 440, doesn't mean much, a little over a minute if he can hit 140 and he could. Turned down road that dead ended in a farmers yard. Bummer. Simple solution to keep driving was get a second license in another name. Yup, I was a speed demon. It wasn't that hard 35 years ago. Finally got caught at that. Revoked for 1 year. Finally sold sports cars. Went to 4x4s. Kept it fairly clean for the last 30 years. Maybe one speeding ticket every 3 years or so for a while then almost never. Have been stopped in Montana a couple times since I moved home but just get a warning. Old guy. I did get one in Idaho though about 5 years ago. Cruising down a 2 lane road at about 65. Just being normal because in Montana 2 lane is 70mph. Just space out that Idaho was 55 on 2 lane.
I still bump 5 mph over sometimes, but that about it and with the speed limit on 2 lane being 70 and the interstate 80 that's fast enough. Here the HPs usually won't stop you at 5 mph over.
