Lane splitting is something that comes up before state legislatures regularly.
Wikipedia defines lane splitting as "riding a bicycle or motorcycle between lanes or rows of slow moving or stopped traffic moving in the same direction. It is sometimes called lane sharing, whitelining, filtering, or stripe-riding."
