“Do they just not monitor it?”
No idea. I used to take it home to avoid Austin traffic. I would be doing 100 in a Camry and cars would be passing me.
Now I take highway 35 to Austin every day and I do between 80-95 if there are no cars in front of me. Speed limit there is 70.
LOL, I live in MA, and they have a belt around boston (128/95) and it isn’t uncommon to do 80-85 with a car 10 feet in front and 10 feet behind in the left lane.
I have driven it every day for the past 30 years, so it is second nature, but my poor wife nearly has a stroke driving in it.
The stupid speed limit is 55, and I always think they like it that way so they can pull you over anytime they want...
