I generally ride a big steel frame bike. It triggers all of the loops I cross. Lord save us from the cities that relegate bikes to routes laid out in quiet neighborhoods. I know one route that has 6 stop signs in 10 blocks.
Two rights and a U? I did one several years ago. I have also made the right turn looped into a driveway, foot down, made a legal left turn, Right turn, and on my way. By the time I finished it all the light had cycled anyway so I did not bother after that. Going to the head of the queue? Usually I stop one car back and in front of the second vehicle and make eye contact. Too many times the first car makes a right turn without warning.

Life is not a race and I do not have medical coverage so I do not take too many chances.
