Ok, so being a long term resident of the Peninsula and a long term rider I am very used to the influx of bikes down here at the first sign of summer. Today at work I had the unfortunate luck to turn onto the Esplanade from one of the feeder roads, encountering a group of bikes wobbling their way south... First up, about half the group appeared oblivious to my LIGHTS AND SIRENS. My work vehicle is a big white van, with lots of bright and noisy attachments. How they failed to see and hear me is a mystery, would have been a very different outcome if my shirt was a light blue, instead of dark. Then one of the group did realise I was attempting to enter the road, and grabbed a big handful. Mate, your emergency stopping skills aren't bad however you caused your mates behind to scatter like tenpins, only inches away from taking out you and eachother. Near misses for more than one... Thanks for letting me in though > So, now the big, white, noisy and brightly lit van has separated this bunch into two and is attempting to make good progress south. Interesting to ponder that these guys may just be members of the Hearing Impaired MC as we watched a couple of the lead guys overtaking rather inappropriately to the tune of our siren. Oh, by inappropriate I mean blind corners and double white lines in moderate traffic. So now were are well into the Esplanade itself, I'm trying to make progress but these guys just won't yield. Siren on-off-on-off-horn-siren, repeat but the forward half of their group are simply unaware that we are there. One by one they finally find their mirrors and allowed me through, several more near misses here, panic when they finally realise I'm there, hard braking into gravel, another 'almost' rear-ender and one guy so close to side swiping one of his companions that they may have actually touched. Finally I have them all behind me, and by behind I mean a few millimeters behind for one. Mate, I'm about to brake soon, and turn suddenly. If you really want to get scraped up and taken to the Alfred in the back of my van that's fine, but can you at least have your accident without involving me, or making me a witness? Amusingly, a fair number of this group, maybe a third, were wearing high visibility safety vests. The irony was not lost on me. I can just hear them now, post incident, "How didn't he see me mate? I was wearing this fancy high vis vest while I crossed double whites on a blind corner at more than 20k's over the limit. I can't believe he didn't see me". Oh well I guess the vests do make it easier for the plods to notice you... Guys, it could have been YOUR FUGGEN FRIEND/FAMILY/WHATEVER, that I was trying to get to, and I didn't need you lot trying to create work in front of me. It has been many years since I have seen such a poor display of skill and roadcraft.
