Shake don't Wag?

There you are riding your bike down the road, minding your own business, when a motorist pulls up alongside you, and gives you a piece of his/her mind.

Many cyclists just ignore it, and pedal on, others return the favor.

Then there are some, like Bill Strickland, of Sitting In, at Bicycling.com.

As long as the motorist doesn't pull a gun on you it's a great idea. ;-D

Oh,  and riding safely puts you in the right from the get go.

Commenters address the safety concerns of this story, and I like Bill's reply in comments.
