I've been a DER for over 25 years (FAA, and EASA since it was formed). I've seen volumes of new regulations, interpretations, Advisory Circulars, etc. over that time. Without exception, they have added to the time, cost, and manpower required to certify an aircraft or aircraft change.
Maybe 5% have had any effect on safety, and not all were for the better.
In fact the greater the safety improvement a change will provide, the longer it takes and the harder it is to certify
Adding new regulations is almost never the answer.
BTW, I don't think it makes much difference what sort of flying machine you're on, if you hit power lines your chance of having a good day are not in your favor
