Troglodyte or Human

When I saw the Ford F150 in the Publix parking lot I had feelings ranging from disgust to humor. Should I put aside my sense of political correctness and accept that the driver simply has a macabre sense of humor or be dismayed because the driver might be one of the people who might have passed to close to me as I was riding?

I concluded that the best way to dismiss the possible troglodyte behind the wheel of the  monument of excess was to imagine the insurance rate he, she or (more likely) it faced for wretched driving habits.
