Thanks to those that stood up and put forward the case that you do not make changes of this type without proof and more importantly, including those effected.
I think this is good news in a whole lot of ways. If a better way to improve Safety can come out of this, then that's a great thing.
Safety needs to be based on properly researched information.
But the first thing, like Jon said, is to decide what it is that is trying to be achieved, no use putting forward solutions when the Goal or the Problem is not clearly defined.
For mine, the major Goal for any Motorsport Organisation is to make sure that the Safety Rules (in this case for Land Speed Vehicles) are first not fundamentally flawed and then developed to keep up with higher levels of performance and available Technologies, whether that's Tube Size, Fire control, Seat Belts, whatever.
In this case, the question for me was, will a larger diameter Roll Cage Tubing actually
improve the safety of those racing a Motorcycle Streamliner?
I did not see any proof that it would do this.
So if this is the Goal or the intention, then make sure that the basic design requirements are what is needed, to then design a Safe Motorcycle Streamliner, no more and certainly no less.
Looking around at the direction that Motorsport Safety has been heading for a while, I'd say it's making sure the Driver is contained in a "Safety Cell" that not
just stays intact, but reduces the forces that can cause Fatal injuries to the occupant.
It's not much good having a Vehicle that stays completely in one piece, but the Driver inside is not.
