They’re a little slow on the uptake. I spent the entire time that I drove from California to northeastern Ohio on I-80 going 80 MPH.
There are plenty of police officers keeping an eye on the traffic. I saw one guy who was driving like a jerk and going at least 20 MPH faster than the rest of us.
Drove right by him while he was getting a ticket, too. Going 80.
My favorite is how the OK turnpike toll-takers look at the entrance time and remark, “you’ve made good time today”. ;’)
