When you're speeding and someone stays behind you at the same pace, in the hopes that -- should a cop be nearby -- you'll get pulled over instead of them.
Pretty much a mild flex, basically saying I don’t care about you at all. I haven’t even had a second thought, literally not concerned. Radar picks up everything you not being one of them..
Her- You’re not gonna start problems with my new boyfriend are you?
Me- You must like to stir the pot. That bum isn’t on my radar.
