Add in animals major cause outside rider error maybe biggest cause.
And spare a thought for those first on the scene of an accident,at least if wearing protective gear the scene will be less traumatic,the fact you have shorts and t shirt will make injuries worse than leather wearing rider,won't apply at 160km crash for sure.
I saw the effects of a low speed crash on a farm race,guy was picking out shingle from his knee for weeks,is this relevant a work crash to road,probably not,but tarseal is harder than gravel,and at 50km I wouldn't like to crash without my gear.
I crashed 20 years ago on my ER185,90 degree bend by my homedoing 30km and slippery road due to rain,still have scar on hand,and knee,was going to dairy 300mts away,had boots on,but sweatshirt and jeans dont stop much.
