What are some clues your vehicle is way too common?

If you came to a traffic stop and either behind you or on one of the side roads you met yourself (the same model vehicle you are driving with the same styling) would that be a clue your vehicle is too common? If you left a store and missed you’re the row that you parked in but thought you hadn’t because there was a car same make, color, and model as yours etc. there, would that be a clue? What about being on the freeway traveling at least 30 miles and overtaking or being overtaken by a vehicle as you are driving, a clue? What if while the aforementioned occurrence was happening, you were trailing or being tailed by the make and model vehicle you are driving, would that tell you that your vehicle is too common?
