That was my point.... I'm in favour of unlimited speed for those of us paying attention...
I think we may have wires crossed here somewhere! I read your post as that is was good to have SPECS everywhere, doing us for +1mph.... but obviously not. No real point in owning an RS4 if that was true.
Most motorway issues other than actual crashes/incidents are either people tailgating and randomly braking, or those idiots with cones blocking off 2 lanes so someone can change a tyre! I'm all for safety, and someday it'll be me changing a tyre, but I think I'll cope without the cones!
I like to think that my driving is 'above' average (40 points in 20 years, but only 1 accident), and I adhere to the 'system' that the rozzers use - Roadcraft should really be made part of the highway code. That would probably save many lives by getting some of the more remedial drivers off the road.
For your point on overtaking, using the system to overtake a car doing 45 in a 60mph, you'll probably hit around 100mph in an RS4.... as I did in mine. Trick is to remember to slow down afterwards..... I often forget to do that though
As for the 20mph near schools etc, probably a good idea. Although driving using the system automatically makes you slow down because of hazards and road conditions.
I shall be reading my new copy of Roadcraft on the way to Australia...maybe twice!
