first, i never blow red lights. mind you i've got maybe five routes that i ride really frequently and i've got my light timing down so i really only hit a red light maybe twice a week.
stop signs... well that's a disaster story. at least once a day i stop at a two way (foot down and all) and have the cross traffic stop and beckon me to cross like i'm a ped or something. i've taken to grabbing the centre of the lane at stop signs in an attempt to make it crystal frickin' clear that i'm a vehicle, but it doesn't do a damn thing. i usually just wait them out 'til they go.
four ways i usually do the slow-then-blow routine, but they're all in residential neighbourhoods.
