Advanced for both you AND the cops!
Some cops do like sitting on exits to hide with their radar guns 😒 obviously better than sitting on the shoulder though. Imagine having kids at home and risking your life while already having a dangerous job. Pulling people over on the shoulder instead of taking them to the next exit is the worst.
Mobile speed cameras huh, I’ve seen those - in photos from Europe.
Cops radaring, not an uncommon sight in California! And Southern California seems to have cops all over the highways.
