I think the currency regs for passenger carriage are good and correct.
I have read many accident reports where passengers got killed and it is especially sad because they probably though the pilot was really competent. Little did they know. Doubly sad when a kid get skilled.
And it rarely is a landing accident (which could happen to anybody); those are rarely fatal. Most fatal crashes involve some Grade A stupidity like squeezing between SFC and OVC 008 ... 006 ... 004 etc.
The thing which is very wrong with the UK CAA regs is that you cannot renew your passenger currency with another normal PPL holder who is current. The US regs allow you to do that, I believe, which is a much smarter risk management.
