Do you ever feel vulnerable with the top down?

I had something happen in the back woods of Ohio last week (Southern Ohio near West Virginia). I was driving my Mercedes which is very rare around those parts. I was driving about 60 in a 55 and quickly approached this old pick-up truck that was doing about 40. I couldn't pass and kept a safe distance but all of a sudden he slammed on his brakes so I would either crash or hit him (fortunately I had the engineering of Mercedes behind me and swiftly went around). Him and his friend looked at me and extended a back woods greeting (middle finger) and I just kept going. I drive a lot (about 40,000 miles per year) and this happens a good bit when I am rolling in a nicer car.
