My guts are still churning, even hours and hours later... I had the misfortune to lay eyes on a video that a fellow biker sent me... it's a 3 lane traffic scene, focused on a bend and it shows a biker getting tapped from behind by a large truck and then getting run over and mashed out of existence. This vid has had a big impact on me. It's truly horrific. Infact, I'd say I'm partially traumatised. This post is not about the vid per se' but what it reinforced in terms of roadcraft. The bottom line is you absolutely MUST jealously gaurd and defend your space. In traffic, SPACE is your very first and most important line of defence. You can't afford to let your mind wander off. If you notice your mind wandering off, give yourself a clip across the back of the head and get back on the job. Some pointers for safely negotiating traffic on two wheels: Maintain as much space / buffer around you as possible. Position yourself for maximum visibility. Maintain a mental radar map of the traffic around you. Ride proactively. Defend proactively. When changing lanes, head check and speed up - then resume normal speed. (The speeding up will help cover for a crap head check as it will help clear the space beside you) Be predictable. ...that's enough from me. Ride safe.
