One of the reasons the 25 mile rule was scrapped was because it could not be enforced. How is the "Insight of Ground and Clear of Cloud" rule enforced, or the X wind limits or the weight and balance etc. Basically if you bend it, the insurance will not pay and if you are still alive, the CAA will prosecute. So can't that rule still apply, say to 50 miles.
The NPPL should be a step into flying, with a carrot to entice further training, so if it restricted (and lets face it, the restrictions at the moment are nothing to talk of), the NPPL pilot will have an incentive to train further.
