On one hand, you're probably joking but on the other hand you also ride a bike...
So, here is my general experiences on speeding and such in the relevant parts of Texas (mostly):
There are a lot of police around DFW but still, plenty of people go 70 to 85 regardless of the posted speed if it's a highway (with a frontage road). There are still a lot of highways with a posted 60 to 65 MPH (that doesn't mean people don't get pulled over at 75/80 in a 60).
On my numerous drives from Austin to DFW and from DFW through Oklahoma, I usually stayed within 10 mph of the posted (once I got out of DFW). Of those numerous trips, I can only recall being pulled over twice. Once was for expired tags in Ft. Worth, which I got a ticket for and a second, in Sherman (by a Trooper) for ~12 over, no front plate, and expired registration... which I got a warning for all three.
Also, I've seen numerous people on 69 in OK getting the various elective and optional taxes when driving though those little small towns.
The only time I have passed a patrol car going close to 30 mph over was a Houston city police officer at around 60 mph in a 35... which he/she did not pull me over for (it was in the hood, so maybe he had better things to do).
