I ran across this old thread when looking for info on wiper adjustment, and thought I'd share my story.
My wife and I were just finishing dessert at a sidewalk table in a restaurant in Sarasota... celebrating our new addition to the family (the smart). With the car being parked not far away, I noticed an older gentleman circling the car several times... looking at it from all angles, looking in the windows... and then from his pocket he pulled out a US flag... one of those that clips onto your car window, and put it under my wiper and then walked away.
Thanks!!!
