It doesn't help that the laws vary from state to state and city to city. In Oregon, it is illegal for a driver to enter the bike lane prior to making a right turn. This leaves right turning drivers blocking cars in their lane while trying to judge an approaching bike's speed and distance using their rear and side mirrors. California's law makes more sense, even though it sounds like too many drivers don't establish a position on the road that makes their intention to turn clear to cyclists.
