So this morning I decided to lane filter at some lights where there's lots of traffic. I get in front and this skinny dude in his 40s driving a brand new GTI starts honking, gets very close to my bike and winds down the window. He starts yelling that what I'm doing is illegal... I just replied 'good on you' - he calls me a d1ckh3ad. Lights go green and as I need to turn left a couple hundreds of meters from the lights, I tried to overtake him but since I ride a 250cc so I can't overpower the GTI so I get behind him. We keep moving and I indicate to change lanes... he makes a sudden move and gets in front of me... then he suddenly breaks - I had to emergency break but managed to keep control of the bike. By that point, I'm really angry so I take the left lane quickly and wave good bye... a couple of kms later he is still behind me at some lights and tries to cut me from the left but he's blocked by a truck. He got stuck at the lights and I managed to go, keeping an eye on the mirrors just in case he appears again. I've been riding for almost a year... and first time that a cage gets pissed off because I lane filter. At the last lights I just wanted to stop and kick his 4rse..
