Do you (A) stick your left forearm up or (B) stick your right arm out? I have been using (B) under the reasoning that it is more intuitive. However, someone pointed out to me that (A) is more visible to cars since the lane position of the driver's seat is usually to the left of a cyclist's lane position. So now I don't know what to do. Which is better? edit:
Interchange "left" and "right" if you live in the UK or another country where people travel on the left side of the road.
