I had a guy cruise by me on the Interstate in a new Audi convertible. The top is down and his right hand is draped over the top of the windscreen. Was he being cool, airing his armpit, or preventing the trim from rattling?

I could have put my hand over the forward edge of the my sunroof, but I would have felt silly.

 

If it didn't look cool to you, then it wasn't that.

 

Agreed....perhaps he injured his arm and had to keep it elevated. Otherwise .

 

After giving it more thought, perhaps he was drying his nails? Which reminds me - I need to make an appointment with my manicurist.
