I donno CB... frankly I like seeing sharrows... and I am seeing more and more of them. Yeah, they really do mean nothing, but like this stupid sign I keep posting...
Sharrows just serve to remind motorists that they are not the only road users out there... just as the jagged lines in HI remind motorists to watch for peds.
It all comes down to either having to constantly remind drivers or go the full Monderman route and seeing what happens.
