A couple of places on my commute I come up to an intersection and turn left. If the light is green I have to slow, brake, watch for bumps, watch for traffic from every direction except straight up or straight down, turn left sometimes with traffic and sometimes without. How can I do all that one handed? If you are in the left turn lane signaling is kinda redundant. I have always wondered if the control fo the bike or signaling is safest.
