Must be over five years ago now, but I was on the A50 (in Tiger) coming back from Crewe and came across some guy in a rough-looking Melina V6. I paced him for a little while, then pulled in front of him (at a decent distance of course).
Absolutely no recognition or reaction from him (or his young girl passenger). We may as well have both been in base-level Golfs or something.
Sometimes a car is... just a car, I guess.
