unless posted red light means stop and if safe proceed ( we're not talking going through the intersection!). these rolling or hollywood stops are not legal and endanger life...think about it when some driver rolls the light or the stop sign and you hit him/her.
life's too short for this "cool" behavior .
i have been at he scene a few seconds after this type of accident and trust me it wasn't pretty. the second gained with the rolling stop was lost while waiting for the ems, much less the time time to recuperate.
