Well I had my nearest miss today, I still don't know if I was a little jaded/tired from the night before, if it was because I was following another biker, If I hadnt seen some warning sign or if the guy just pulled the "manouver" so quickly but I've now learned something new.
I can lock the brakes, perform a partial stoppie <sp skid the bike, release the brakes, steer, stand up on the pegs to use my body to balance the bike again squeeze my leg against the tank to hope the crash bar takes the impact not it and sh!t myself all in a split second, well the length of time it takes to cover the distance from a Corsa's rear wheel to front wheel. Arent humans amazing

( ok I didnt quite manage the last one but it certainly puckered!)
No gaps in the left hand lane no gaps in the right me filtering down the middle, Vauxhall Corsa turned the wheel, put his indicator on, started to move, and shoulder checked once he moved all in one fluid movement

nowhere for him to go and would only serve to tell the people in the inside lane he wanted to be into that lane. He got a lot of head shaking for that one
So in the past month I've had a near miss with a fox that was crossing - brake hard, decided not to - release brake, changed its mind again, thinking the bike looked less threatening than the cars on the other side of the road and turned round again - brake hard and listen to the rrrrrrrrt of the ABS of the taxi in the outside lane overtaking me.
A colision with a cyclist:- I'm filtering quite happily up the inside of stationary traffic (there is a dotted on road cycle lane there so drivers do keep well over), see a gap appearing at a junction on my left, brake because I anticipate someone turning throught the traffic sure enough car appears, sees me, stops, realises I've stopped and continues to turn with a wave, then I feel a bump!
I was stopped as I was taught, rear brake on, left foot down, both hands on bars, I turned to my left and theres a cyclist sprawled half on/off the pavement. If I hadn't stopped chances are he would have been taken out by the turning car. As it was he picked up the bike and proceeded to ride along the pavement. More head shaking by me. Slight mark on top box but thats about it.
& tonight

I waived to a cruiser rider who pulled up behind me at the traffic lights and then couldn't filter once we moved away because of his cow horn / ape hanger handle bars comlete with indicators mounted on then were too wide
Filtering is great, and the whole reason I got into bikes, but you have to be so aware/paranoid/observant at all times. As Base told me if you filter the same route for years with no problems a bit of complacency can very easily creep in. Hopefully it hadnt & hasn't but today was certainly a wake up call to re-enforce the dangers!
