the law is not for bikers to just blow the light, its for the lights that dont cycle to green within a reasonable amount of time while you are sitting there. i dont know if there is a law in Michigan for this but almost everynight on my way home from work, on my bike, i have to "run" a red light turning left because it will not change. i have sat through 5 complete cycles before, now i wait 2 and the go.
