Ironically, I have long argued that it is somewhat irresponsible (both of the authorities and individual pilots) to allow people who are not capable of instrument flight to command an aircraft.
Can you imagine a "good weather" driving licence, where the driver is disqualified from entering rain, and is likely to crash if he does?
The tiny amount of instrument flying in the PPL is clearly inadequate.
So, if I were King, I'd probably make the EIR a compulsory part of the PPL. Don't worry, though. Neither of my parents is a Queen
