DAYTIME speeds vs. nightime
I drove through Montana a few years ago , where the DAYTIME speed is "reasonable & prudent". This is essentially the "unlimited" speed of Germany's Autobahn. This means with NOBODY around you can go pretty much as fast as you care to.
With other traffic around (including Montana State Troopers) you probably are immune from a traffic ticket up to 85 MPH or so.
OTOH, the NIGHTTIME speedlimit is 65 MPH, and going as little as 68MPH CAN & WILL RESULT IN A TICKET. (Factor in the fact that MANY judges DO NOT LIKE the thinking that "reasonable & prudent" is an invitation to goofballs to drive like maniacs in Montana, and you learn to watch you speed after the sun goes down...)
I bring this up because the odds of something being in/on the road AT NIGHT is MUCH HIGHER EVEN IN LI. I would STRONGLY recomend confining "high speed runs" to DAYLIGHT hours! For your own safety, and that of others, REDUCE, DON"T INCREASE your speeds at night!
Your first concern should ALWAYS be safety, even when in technical vioaltion of the law! The busy-ness of the police and odds of arrest SHOULD NOT be a factor in attempts at high speed motoring.
