Doesn't happen too often to me. Although, last year some retard was tailgating me in downtown golden. I slowed down, he got pissed, and eventually passed me on Indiana. He then drives the limit, :roll: so I stay behind him. He turns into MY neighborhood trying to get away from me. He pulls into a side street that is a culdesac, and I continue on my merry way.
When people flip me the bird I usually grin and wave back, for some reason this seems to drive them into a frenzy.
