as far as the trackstanding goes, i vary, if i'm arriving at the lights late and they're gonna change i'll slow roll then be forced into one as they invariably change 15 seconds after i reach the bike box, but if they hit red as i arrive then i'll usually get off, though sometimes i'll just wait in the trackstand, for a more rapid departure, what they really need is bmx style gates in cycle lanes so these sprinting folk can really get their snap on….
