There is a material disparity between the skill level and rider reaction time of professional tour riders and the average Bunch Rider

Many riders in the Annual Popular Professional Bicycle Road Rides can -

(i)         ride in close, large bunches at significant speed;

(ii)        regain control of their bike from a skid when a fall appears inevitable;

(iii)       descend steep mountains on straight dry road sections at around 100km/p/h;

(iv)       suffer nasty falls and avoid serious injury most of the time due to their age and physical strength; and

(v)        display enormous skills when they win a stage, zipping up their jersey, saluting the crowd with no hands on their handle bars, yet control their bicycle when mere mortals would veer off line and likely plummet to the roadway.

Alas, just as annual Formula One and the Motorcycle Grand Prix races mentioned in Rationale For Professional Motor Vehicle Racing influence some car drivers and motor bike riders to speed recklessly and/or dangerously, the Annual Popular Professional Bicycle Road Rides have similarly influenced some road cyclists in Bunch Rides to take unnecessary risks because they believe they have greater skills than they actually possess.

The fact that a 20 or 30 year old muscular body can withstand serious trauma accidents far better than older less muscular adults also contributes to Avoidable Trauma Bicycle Accidents.  Evidencing rugby footballers 'et al' experience bone crushing 'hits', and bounce back up almost instantaneously, is a testament to the significant disparities between the skill levels and physical attributes of many of our sporting heroes and their adult admirers, some of whom seek to emulate their idols.
