I used to drive a 1991 Suzuki Cappuccino - a tiny right-hand drive kei sports car. The first couple of years I drove it, the police pulled me over on a regular basis - no tickets issued but lots of questions asked.
One time while I was waiting for a light, an officer knocked on my window (which is somewhat startling)... I rolled it down and he excitedly asked "What kind of car is this?!"
That's just not enough motive to waste someone's time.
And, no offense intended, that car is not that interesting. I guess policing must be boring.
