Let me just quote the first line in the good Madison doctor's article that you can read in full here (Wisconsin State Journal)

"I was riding home on my bicycle from my clinic on Madison's South Side recently when I passed an apparently stalled minivan at an intersection in a quiet residential neighborhood."

It's a good thing the Madison Doctor, Dipesh Navsaria, clarified that he rides a Bicycle and not a car when commuting to work.  He wouldn't want to anger any of the locals.

Dr. Navsaria went on to (comically in my opinion) describe his experience with someone who would dare question his education and training as it pertains to the H1N1 Flu vaccination.

Of course he admits that he did not actually try to engage her on this topic but just "mused on an odd aspect of the encounter" as he peddled home.

I wonder if he was just afraid that her argument would have been better than his.
