I see your point, to a point, but it also chimes of one of those circular type discussions too. (e.g.: kids were much better behaved back in my day...).
Was riding a motorcycle not considered dangerous back in the <insert decade>? Did this element not influence your attraction to bikes even a little? I'm sure skinny tyres and shoddy brakes, etc, all contributed to the image. I'm sure part of the thrill was pushing your bike to the limits of its ability and perhaps something that perversely contributed to the safety of riding was being able to know exactly what the limitations of your machine were.
Now bikes are more reliable (unless I’ve been near them) and more stable and you're less likely to come a cropper because you've run out of tyre/brakes failed/you've run over the red-flag carrying chap walking in front. In other words, you're now almost certain to reach the limitations of your own talent before ever getting near that of the bike. So when you see a BMW S1000RR scrapping the pegs doing 90 through some twisties that means you'll be able to do it too-right?
How to you address this? More nannying and insist that people who are wanting to buy an 180bhp bike are tested as competent on an 180bhp bike? An acceptance that these rocket-ship riders are themselves going to be replaced by Tron-like ninja's in a generation’s time, and they'll no doubt be more moaning? How about live and let live? The wheel turns. If someone wants to 50 pence every corner and blast at mach 2 along a straight, that's their business. If they want to overtake on double whites or swerve into oncoming traffic, that's their business.
I am in total agreement that the speed limits posted in the UK are antiquated from a bygone era. I am in agreement there is too much traffic, with too many income cameras. I agree that the roads in the UK are in a shocking state. I am also in agreement that there are too many dickhead riders out on the road, including myself. There was a time when I was getting up at 5am just to enjoy a ride out. Now, I’m enjoying my commute and trips to France (where the roads are miles better). I don't really do pleasure riding anymore, not at the weekend. The A272 mentioned is a few miles from me and you can barely move there on a Sunday because of traffic volume/cops, so what's the point?
