Tend to agree Arrib and am along the lines that every circuit has places where we have seen extremely severe injury or death at times in cars and/or bikes so where does the 'motorsports is dangerous' component come to effect?
Yes, we need to try to make the sport as safe as possible by the removal of as many unnecessary hazards as possible but we also have to be realistic (as unpalatable as that may sound) in that without cars using these circuits, then bike racing may not exist as many venues would receive greater income from cars which may go some way to subsidising the bikes.
For mine I have always agreed with CS in terms of the tarmac runoff component in that it is not a deterrent but in some instances is rather seen as an extension of the track and at other times, when a rider has fallen it does little to slow the rider down. As such for me, motorcycle racing in general needs to look at developing solutions that can be readily implemented that will act as a deterrent and where needed, improve the safety of the competitors, but at the same time I realise that there is likely no easy or ready fix.
We also need to understand that freak incidents will occur from time to time and whilst nobody wants to see deaths or injury, it is a component of the sport and what we need to do is learn and try to improve to lessen the risks whilst acknowledging that the risks will always exist.
My view may be archaic to some, but having been around and seen many of the circuits on the eastern australian seaboard I can say without fear of contradictory proof, that motorcycling lags a long way behind cars in the thoughts of circuit owners, so it is up to us to improve the sport and safety ourselves
