Shouldn't be a problem to any of us as I've noticed we all ride sensibly and at a steady pace well below the posted limits... you didn't happen to notice what sort of bikes they are did you?
(looks for smiley of walking away whistling noncholantly...)
All sorts, sports bikes, Adventure bikes, tourers etc. In other words most genres covered and in standard colours too.
Intersetingly whilst riding on Sunday morning my brother and I came across the archetypal idiot who threw his bike (and himself) into a ravine on the Via Gellia road due to taking a bend far too fast (but probably within the speed limit, it's national at the point of the accident), panicked and hit the brakes. Result, rider and bike leave road and take trip into ravine. Conclusion, two police cars plus officers, 1 ambulance with specialist spinal stretcher on board plus fire engine with lifting tackle and gear to get said rider and bike out of ravine. My brother and I were not surprised as we see this all too frequently and both agreed why the police in Derbyshire get so fed up with the antics of some riders. More ammunition for the politicians to aim squarely at all of us I's afraid.
Strangely 5 minutes further down the road we noted the A6 was shut and again assumed it was another motorcycle accident. Truth is stranger than fiction - some poor motorcyclist was riding through the heavily wooded area about three miles from Cromford when a branch fell off a tree and killed him. Unbelievable and tragic indeed.
As has been pointed out elsewhere in this thread the best way to avoid the aggravation is too ride carefully and sensibly, you can still enjoy the ride. That being said it doesn't hurt to be aware of covert measures in place.
Derbyshire and Staffordshire have many beautiful and rewarding riding roads well away from hose frequented by the lunatic fringe. These are mu preferred routes and easily sought out with the aid of a good map.
Incidentally, anybody who enjoys or is interested in industrial engines might want to take a visit to the Anson Engine Museum
http://www.enginemuseum.org/ just north of Buxton. A great place to visit.
