I agree with the second point (when cycling with kids from school I teach them to wave and smile at DDs and avoid shouting), I think the first is well-intentioned but is part of the perception that cycling is dangerous.
"Everyone else on the road is a complete nutter and out to get you. Keep that in mind and you should be alright."Any activity is dangerous when carried out by an idiot (just take a look in your local A&E),
But He meant it with regards to anytime we were using the roads "walking, cycling, motorbiking, or driving".
It doesn't matter as there is always someone "Bigger" than you, that you have no control over.
The point was it is "Bloody dangerous" on the roads, so keep your wits about you & don't be stupid.
Just because you are obeying the rules doesn't mean 'everyone else is'!
P.S.
He was a keen cyclist and held licences for 'almost' every category inc trains, tracked vehicles & aircraft.
Now that he is sadly no longer with us it's safe to say that his job included looking after a lot of very obnoxious people all over the world, Although some were OK.
