Most motorists are unaware of this, but they have the same rights and have to obey the same laws as the driver of any other vehicle unless the road specifically posts that only motor vehicles are permitted. That includes indicating intention by pertinent signals: Left, right, and decelerating. [The signals to be used by cyclists are different from motorists and vary from state to state.] Riding on the berm is actually a violation; vehicles of any kind permitted on a road are not supposed to ride the berm, which is for emergency use.
The part about bikes being entitled to a full lane is true and especially annoying, galling and outrageous.
I didn;t know about them not entitled to ride 2 or more abreast. Good to know. ("Neah, ah-ah", Snidely Whiplash moustache twirl)
Riding motorcycles two abreast is legal in my state, Washington.
I am in a more conservative part of Washington State and have noticed the road bikers (bicyclists) over here are mostly sans the swollen heads and inflated egos because they tend to be...well, conservative. Have never witnessed the militant tactics on this side of the state but understand they are common in Seattle.
