Hell they do 85-90 in downtown Atlanta.  Being from Florida, OP speaks truth.   I got pulled over on the Turnpike heading back to Tallahassee after watching  the Noles stomp a mudhole in the Hurricanes' asses.   I was doing 97 and got a warning.   The only place it is always bad is Madison County.  Sheriff's cars run radar on I-10 trying to fill that poor ass cesspool's coffers.

Was  riding back from St. Augustine with my ex, (sorry no pics, deleted them)  who is from Kalifornistan,  when we got pulled for 3 over in Madison on I-10.   She was furious she couldn't flirt out of it and even more angry because I told her not to speed  thru there in  the first place. I might have reminded her after the fact that I did so inform her prior.  She was more fun when she was pissed.

I just laugh my ass off when I see some asshole pushing triple digits on the highway nailing a big chunk of rubber left behind by a truck blowout. That is when you get to see how much driving skill they actually have.

I'm impressed

 

for all the people from Florida saying traffic does not routinely go over 90 or 100mph,,,, you are just not paying attention or something. I have driven all over the state and anytime I am on the Interstate or Turnpike people are constantly doing it.

Lots of roads in Texas that are the same way.  I was running 90 on the way home tonight and getting passed left and right.  
In south Texas the speed limit is 80 or 85.  My F250 shuts off at 97 so you do have to plan your passes and make sure you have the room you need to make the pass before it cuts out.

A friend of my Sons just got pulled over a couple months ago for doing 93 in a 50, immediately lost his license for a year, he has had a couple other violations within the last year that didn't help his cause any.

i wouldnt  thank any armed,dog shootin revenue collector. warning or ticket or whatever.    if you didnt cause a wreck, he had no business stopping you at all.
