I have written to my euro MP's about this I have got back a very "standard" response!!! I have asked to meet one of them to talk about this. I am not hopeful, a counter argument is of you want the quickest and more powerful cars go buy an off the shelf one...... This will force people to do this. How ever what about things like Caterham's, Lotus 7's or custom tricycles?
It is my opinion that the worst that could be done is forcing some sort of "q reg" equivalence! Even this however will be difficult. There is the SVT type test and that seems fine, but a bit extreme for lightly modified vehicles. I think the only way forwards is to be more involved with the people who want to change the law so we can influence and educate them so any future legislation is "more" sensible.
Most of the politicians have NO idea about engineering in general let alone what a rose joint, engine map, distributor-less ignition or gas flowed cylinder heads are! These are all normal upgrades to do, let alone something a bit exiting like NOS.
As they don't understand they are frightened, therefore inclined to ban them! The other problem is not only within the car "scene" but in society in general is about speed and risk.
95% of road users do it, from the mom on the school run rushing get there little one(s) in on time, to the executive late for an important meeting, to us having fun on the open road.
Faster cars do allow for more serous abuse but better suspension and better brakes make for better stopping distances! Besides it is not the car, it is the driver!
One of my vehicles is a 50cc pap limited to 30! I have yet to keep up with the traffic flow let alone overtake any other motor vehicle even in 20 zone's except if its jammed up with traffic. They literally brush past me in there hurry to get "there".
“Risk aversion” is the new buzz phrase and current western society is terrified of risk, there are examples of this everywhere, but it is risk that allows us to make progress as a society and on the individual basis when successfully negotiated it is part of what makes you feel “very alive” we all have to lean to deal with it and asses it better not eliminate it.
