Here's my problem with the "just don't speed" or "just don't break the law" and you'll be fine argument:
I don't remember the specific Supreme Court case name, however, back in the 70's, a police officer pulled over a woman for going over the white line, and long story short, he took her to jail for it. SCOTUS ruled that lieu of issuing a citation or fine, a police officer does indeed have the right to take a person to jail for a minor traffic violation.
Now, to/from work every day, it is impossible to not break some type of traffic law - i.e. going over the white line, speeding, stopping over the white line, not signaling soon enough, etc. In essence, every day you could potentially be taken to jail. Now, the question remains - why don't we see more people being taken to jail for minor traffic violations? Answer: it would be costly, and in addition, it would be a PR
nightmare for the police. Thus, officers are allowed to use their discretion when pulling people over or issuing citations.
Overall, the troopers on 355 could choose to not be assholes, or if they did pull people over, they could issue warnings. Unfortunately, troopers preach about the hazards of speeding in an attempt to obfuscate the Illinois State Police's unwritten agenda, which is to make bank on that section of 355.
As I mentioned earlier, I have no problem with people being pulled over for reckless driving - 100+ mph in a car, weaving in and out of lanes, no signaling, not maintaining intervals, etc. But to me, doing 85mph in a straight line on a smooth section of highway isn't a danger to anyone...
