I have to make this comment regarding motorbikes: Just this weekend on a day trip from the Red Kite Park (Fantastic Park mind you) on the A44 a guy passed with a pillion rider at great speed and a few miles down the road, the road was blocked, it appears he and his his wife were seriously injured and air lifted to hospital. It turned out later news he died!
Now as a long time owner and rider of bikes I am not for a minute advocating that people don't ride them, or for that matter go fast, but pace yourself very carefully. When I was riding I rode almost every week let alone every day, my reflexes were tuned to handling a bike notwithstanding avoiding crazy motorists encountered along the way.
The problem as I see it today, all these "old reborn riders" have very powerful bikes, spend half their lives polishing them, then on odd occasions think they can go out and ride to the bikes full potential forgetting they are probably very out of tune with their bikes and end up ...well sadly too many are killed.
