NighthawkNZ
made a comment in another thread that raised alarm bells with me:
This is quite simply, wrong. It has been widely known to be wrong for several decades. I was utterly appalled that the LTNZ & ACC published a 'safety' film in 2005, "Motorcycling in New Zealand: Riding in Groups," suggesting its use.
Why? It leaves riders with no room to manoeuvre and/or in the wrong position on the road. This is demonstrated in the film and can be seen in Nighthawk's attached picture.
(I'm not having a go at Nighthawk, he just triggered the train of thought.)
Consider this: bikes staggered at the 2-second interval. Approaching a left curve, the appropriate behaviour is to move to the right wheel track to increase your visibility around the curve. Do this in staggered formation and the 2-second buffer is now sub-1-second (half of 2 seconds minus a bike length). Watch the film. It happens. And no, suddenly spacing back out to 2 seconds in single file is not a solution - and nor is it suggested in the film, anyway.
So in Nighthwak's pic, the left-side riders cannot manoeuvre into the right hand wheel track, the right-side riders cannot manoeuvre into the left hand wheel track. Both riders are compromised.
The answer of course, is single file at 2 seconds, plus breaks in the group to allow following vehicles to pass. That way every rider is at the optimum position on the road without compromise. This has been the accepted group riding strategy since at least the early eighties, as taught by
Stay Upright Motorcycle Techniques.
What say you?
