Undercover
Driving on highway in Texas, where the highway patrol LOVE their unmarked vehicles that you would never expect to be a cop. I’m talking the Chevy Malibu, the new Ford Mustang fastback (GT version, but no GT badge), etc.
Anyway, we were in the fast lane (70 mph speed limit) and this Malibu is doing 55. My dad proceeds to drive up close to him in an effort to persuade him to move over.
After about a minute of doing this, the car flicks his lights on for about 2 seconds to make us back off, but he blew his cover doing this. He immediately moves over and gets off at the next exit to regain his cover. Story credit: Reddit / Windows_Tech_Support
