i don't think you want to be passing _any_ traffic at much more than 50mph differential speed.
Hang on just a minute there. Surely there is MUCH less risk when PASSING (within say 3 or 4 feet) someone with the quoted speed differential of 50mph than what happens 10 of thousands of times a day on B roads,
LEGAL CLOSING speeds of upto
120mph within 2' of each other with wheels raising a dust cloud from the verges. Doesn't phase most poeple (including myself) in the slightest. (A LOT of 'back roads' round here) As an advanced driver etc. Surely you must appreciate the need for spatial awareness, closing, passing & merging speed judgements which are all honed skills, driving to the prevailing conditions, and a need to believe that every other driver on the road is not trying to kill you!
As for the average family Focus/Escort - neither vehicle was really designed with 100/110mph in mind, and that's reflected in the price, handling & specification. Roads have improved, with newer grippy & easier draining surfaces. Debris, has & always will be there. But I'd rather hit a chunk of rubber in my omega than in a cinquecento!....
Crashes - Kinetic energy, yes it has to go somewhere. Crumple zones, deformable sections etc.
A staged limit, 100mph say for over 25's, with 3 or more years experience wouldn't work - no way to police it. Unless the ANPR could be put to use logging nominated car/driver combinations, but that's getting into almost
PepiPoo territory!
I believe it would be self policing. Much the way that NSL is on B roads. Competent & confident driver with cars/bikes suited to the job would frequent the upper speed. Whereas the more timid, would do what they've been doing for years, dawdling along.
I hear great cries re: Boys Racers in wholly unsuitable cars, conditions & burberry attire dying on every turn & killing innocent motorists. They do that anyway, and legislation will never stop it, only actual police on the ground.
Rant over.
