Riding up the Monash in traffic this morning between the furthest most right lane and the one next to it. I see a learner on a white sports bike looking thing, perhaps a Hyosung naked thing, ahead of me but NOT in my line yet. I am weary of him as he is a bit wobbly and erratic. He pulls out infront of me in my line about 4-5 meters before I would have passed him, I half expected this so was on the break anyway. He makes me slow down and now I am sitting behind him approx 3 car lengths. I'm not pissed - he is a learner, so I give him a break. But the problem isn't me. It is clear he is in over his head and on an under powered bike. He drops a gear to try and split between an Isuzu Ute and another car - both are moving, not stationary. This wouldn't have been a problem for: a. an experienced rider and b. a more powerful bike. The dude in the Isuzu takes offence to this learners attempt to split and accelerates his ute matching the bikes speed, the bike is pretty much giving it full stick and is still stuck right between the Isuzu and another car. The guy in the Izusu is closing the gap between the two cars too! I was watching this and the learner on the white bike was so close to getting crushed, I was sure I'd be pulling over to call an ambulance. Yeah - the learner was attempting to do something above his skill level. Yeah - his bike was too slow to do this. Yeah - he was being stupid for trying.... BUT! The guy in the Isuzu ute was willing to kill someone just because he was on a little bike and tried to pass him in traffic. The learner gave the guy the finger after he got out of the situation and the guy in the Izusu gave it back - he didn't even realize the situation he put him in... If that learner died the law would have blamed the bike rider - but from my point of view the Isuzu would have been at fault, he was making the situation way worse than it need to be.
