Scattercat brings it to the point.
Nothing to do with equipment, routes, rules and so on.
And when looking into things to be changed to reduce accident numbers - we should start at the main problem - the pilot (ego)!
Saying No must become a culture!
Planning with option B a must.
Where you put the figures - depends on area and experience but could be easy done with Radar altimeter or GPS based altitude or even the old Britisch Navy Altitude recognition (if you can sheep legs clearly you´re 200 feet or below)
When cloud brings you below preset figures - no further pressing on, no further cirumnavigate - return or land at the nearest possible spot with no hassle from the authorities playing the game save!
Everybody caught skimming treelines is kindly requested to return his license!
It could be done - but I doubt, that it will become international standard :-(
