Just a small point on comparisons with the USA, and that's the weather.
I'm absolutely all for as much freedom for GA as possible. But how useful would a USA-style VFR corridor be? Englishal gives the example of the LAX corridor, with flights at up to 4500'. I'm not sure there are too many days when a VFR flight along a pre-determined route at 4500' would be possible. Or even 2500', for that matter. I spend lots of time flying VFR at or below 2000' because of clouds higher than that level.
Would people be tempted to push through the corridor regardless, if such a corridor were to exist???
