realistically its unenforceable but i will have a bash.first when new equipment is required the ministry dont cough for it,we do so measuring eqpmnt will cost us.second every make/model vehicle has has different max rev requirements which means that unless you can watch EVERY tester carrying out EVERY TEST just to make sure theyve revved it is a non starter let alone the below mentioned damage risks.what you are essentially asking is for every sports type vehicle to be banned.take a look at how much a ferrari for instance costs in tax let alone vat.dunno if you had noticed but the gvmnt have had whats perhaps best described as an expensive and difficult time just lately so aint gonna be keen on earning less.the key is enforcement of the available laws.this requires police.police require wages,wages cost money-refer to my previous answer.finally i live on a busy main road.my local demographic results in a lot of kids hiring the above mentioned ferraris and similar on weddings and such and ragging the crap outta em up and down the carriageway,all very loud and all with fully manufactured and eu approved emissions/exhaust systems,you think your local boy racer with his bass bin and a member of the wind section of the london philharmonic strapped to his rear bumper is loud?try a PROPER sports car.the police dont seem keen to act…..as a final footnote the resulting ambulance flying down the road shortly afterwards with an equally loud siren(i am assured this is normal and legal!)is a frequent occurence.the accompanying flashing lights dont do the local epileptics a lot of favours either…..
