Germans in particular find the UK IFR Class G rules particularly hard to accept
IFR in Class G is illegal there.
The reality is that the UK, with its GA community approximately same size as Germany and bigger than France and bigger than perhaps the rest of Europe put together, and with a long established culture of flying IMC non-radio, has had
zero mid-airs in IMC since WW2. 1-2 a year in VMC, usually near airfields or with people doing silly low level stuff.
Emotionally this concept is hard to accept, of course. But safety regulation should be based on data, not emotion.
