What di speed is acceptable to ride between lanes through traffic? On the odd accasion I use the bike to work - yesterday for example. I think a safe speed is maximum 40kph, not that I look at the speedo much, but when I do get a chance to look it is usually between 30 and 40. I get pissed off with scooters and the odd superbike that comes screaming up behind me as if I'm the one riding like a doos. I try to find a gap between the cars and pull over so they can pass but I'm not surprised when I sometimes see scooters involved in accidents, last night on the way home I was almost taken out by one because I didnt move over fast enough. Am I just getting too old to ride????
