Yup, if my husband and I are both in the car and see a faster car go past - on cue we both say gleefully “Pace-Car”
Sit back a few car lengths and follow - usually in the middle lane, while they cover the left lane - left lane has spotters [Cops]
End of NASCAR references ;)
I always consider them bait cars, and decoys. Cruising a few lengths behind and to the right. Sometimes they get pissed at the shadow and accelerate out of site. Usually seen a few miles up the road pulled over getting written up.
You and my wife must be twins!
