I wonder if the people who say “accidents are avoidable” ever had an accident. It must be nice being so perfect. 
Even police rozzer motorcyclists must drop their bikes. Didn’t one die recently?
Sure, accidents are avoidable, right up to that point where you chuck your bike up the road, or someone slams into you. Or just stay at home, don’t get on the bike.
Surely it’s all about risk. I’m accepting risk putting my lid on and climbing aboard, more risk filtering, more overtaking. I’ve had 3 offs in the past 8 months - all below 30mph. Not to add grist to the mill but I’m glad I had my textiles or leathers on in each case. They’re still holier than the pope’s undercrackers and I’ve got some cool stories and scars without looking like the elephant man or Shane Ritchie.
