Scottish Elises

Followed a blue scooby through Motherwell. Skye had noticed the Reg numbers as they are the same as ours and then I spotted the blue light on top. Was a flat blue light about a foot wide mounted on what looked like a single roof rack bar. I assume it was some sort of emergency vehicle, anyone else spotted it?

Dont know about the scooby, but on the same lines a D plate 190 merc passed me on the M8 at Hillington last week, with same setup of blue light mounted on a roof bar, he was doing 100+, blue light flashing.
I thought only cops could have blue lights? Strange choice of undercover car....
