Captain Obvious here - but there is definately a 'stay-with-the-pack' mentality that kicks in when you're riding in a group.. Point in case - I "merged" with a group of 3 sportbikes last week that went from downtown area up to CatWoods, and I probably rode more 'aggressively' to stay as a "group" than I would have if alone.. Not past my ability, just 'quicker' than normal.. A few times they left me in the dust (ie. from Bayridge/Front Rd, north up to Bath entrance - a nice straight away, then a big left arc), but city traffic lights re-formed the pack..
