I always nod to people, I remember the first time someone nodded to me and talking to my girlfriend about it when i got home.
It is one of those things that sets us apart to other road users and it would be a shame for people not keep up the tradition.
Must admit that i dont normally nod to scooters unless i cant tell because of the speed i am travelling at. I dont not nod because i am arrogant but more for the fact that they go mad on the little 50's afterwards and i wouldnt want anything to happen to them because they are showing off or something similar.
Going around town on the bike and coming across a scooter is bad enough as they are constantly trying to race you so you end up putting your foot down (should be twisting the throttle) and leaving them behind and breaking a few rules yourself.
Am i rotten or is this the truth for other bikers too??
