possibly even the most important. > even if you don't do it often in traffic, (that's your choice and you have every legal right to take up as much space in a lane as a car.) YOU STILL need to learn it , practice it, master it. how? answer > get of your fat arse and go find an empty carpark. exercise (1.) ride the solid white line. pick a point on the horizon directly above the end of the white line. ride up the line and back down again. again and again and again and again. vary your speeds. do the line in short bursts, pause on the line. stay limp but do not move. breath halfway out and hold it, do not remove your eyes from that point of focus on the horizon. do not look at the line. in traffic this is what you do. you don't look at what you are passing through. you look to the front of the intersection, the end of the white line. you will still see everything. you will see a mirror, you will shift your bars around it. you know where your hands are without needing to look at them. exercise (2.) get some pool noodles or something similar from clarke rubber and mount them on stands. take them to your empty carpark. you don't get the white line this time, because i know you can feel it through your tires. measure the distance between mirror tip to mirror tip on your bike. start by spacing the noodles an additional ten inches apart, practice and repeat, decrease the distance. stagger the pairs of noodles car lengths apart. these are car mirror simulators. notice how you don't need to look at them to see them. they still enter your vision with your eyes locked to your focus point. this sounds difficult, but it's not. if done correctly you will be amazed at how easy it is. the bike will always track true to your focus point on the immediate horizon. the reason for this post is two near misses i've experienced in as many weeks with cars comming directly at me on my side of the road. one came out from behind a truck to overtake it. the other i encountered on a blind corner. he'd chosen my side of the road to veer around a parked car on his side. in both cases i had less than a meter between the curb and the oncomming car. it happens. and one day it will happen to you. become a whiteliner zen master, even just as a hobby. it could oneday save your life. what you do in traffic is your choice, your life. you are alone out there. no-ones helping you. if you don't want to split or filter, then good luck to you. that's your choice. but no ill thought out road traffic law is more important than life and limb. homework > if a car ever tries to share your lane with you, kick the shit out of it at the first safe opportunity to do so. make it known to that driver that he is never to try that shit again on a rider, and in turn you may well save another riders life from that imbecile in the future. no-one else, not the state, not the police, no licence testing requirement, is ever going to teach that guy that lesson. you are the only opportunity he has to learn this.
