A study in the not so distant past, in the usa.
trying to find out why there were so many accidents between motorcyclists and cars at intersections where the car did not give way.
the overriding theme of cars drivers was that once eye contact had been made the car driver thinks " he is smaller than me so does not want to get hurt, so will let me go through".
Conclusion for bikers, Don't make eye contact with car driver.
the big little idea needed more study.
turns out that truck drivers when making eye contact with car drivers thought, " he is smaller than me so does not want to get hurt, so will let me go through".
A pecking order seems to be establishing itself but with an anomally.
when a Hells Angel arrives at an intersection, makes eye contact with car, truck, bike, or whatever. All give way to the angel[}:)].
accidents at intersections involving Hells Angels were non existant.
I kite or windsurf depending only on what I feel like doing at the time. From now on I will wear my colours on my wetsuit.

Keep a very close eye out for them.

PS: I have heard a similar augument to the "let them have one beach and they will take them all " somewhere else. Was it McCarthy?
