Pbike, these folks are just trolls without a driver's license. When they get around to wanting a license, they will have to review some information at the DMV. Here are a few noble excerpts from the Virginia Driver’s Manual:
"Driving is a privilege, not a right. Your driver’s license carries with it a great responsibility to be courteous of other drivers on the roadways and follow state and federal motoring laws.
"Every time you get behind the wheel, you accept responsibility for your actions. You must obey Virginia’s traffic laws, and ensure the safety of you, your passengers, and other motorists, pedestrians and bicyclists on the roadways.
"Bicycles: Bicycles are considered vehicles and have the same right-of-way as motor vehicles. Bicyclists are also expected to obey the same traffic rules and regulations as vehicle drivers; however, many are children who may not know or obey the rules. Slow down when you approach bicyclists. Give them plenty of room when passing and be prepared to stop suddenly. Look for bicycles on all public roads."
