It may sound like I'm having a go at Andy here but I really am not, I am just trying to understand his mind set as its completely alien to me. stay with me here a moment
The comment "the higher the speed the higher the risk" does not ring true with me, a fairer assessment would be the higher the speed the more concentration, practice & skill is needed to be as safe as at lower speeds.
The ability to assess information & react to situations requires all of the above qualities regardless of the speed involved so 50mph may seem fast & difficult for some while 150mph is easy & slow for others, as long as a sensible margin is left & the skill levels are high enough either speed mentioned is equally as safe imo
The story about the biker filtering & doing a silly overtake made me smile, have you ever thought he may have been a quite reasonable rider who was just frustrated at being stuck behind a much slower rider ? in that situation its easy to make a silly mistake & I would guess most of us have done something similar but got away with it in the past
Another thing comes to mind somewhere around this forum you mention how good police riders are, I agree they are good, but many have less experience & less training & less road miles than I & a few others on this forum do, how can it be that they are deemed to be safe at speed while we are not ? sorry but that makes no sense at all
