There are lots of complexities to make a parachute system work,(think of the logic it has to go through before deployment, including if the transmitter is lost) but I agree we need to have one that is tied to a separate kill switch ASAP trust me the authorities will want to see this as well.

Mmmmh, just a tought: why not using the GPS datas for triggering a motor kill switch when you fly out of a virtual fence out of a safety zone.
Let's say you have an operative zone of 300" and a safety zone of 600": you will operate without concern within the operative zone with a good margin around.
Remember that outside the safety zone there are people, properties.... so it's better to crash the copter that making any damage!
Too complicated?

Every system you add you add another thing to fail. These things will never be 100% safe, just do your maintenance, change out parts at the first sign they aren't perfect and you will be much safe than if you add anything new to go wrong.

I agree, as you can see from the writing under my nick!
But today it seems you need more and more feature to be safe when a simple, plain aereonautical mentality should suffice....

My idea was not to avoid a crash of the multirotor but avoiding it to go where is shouldn't...

then you need a failsafe that disconnects the battery and deploys a parachute, if you want the best of both worlds.

Or have something like the attached photo and then tie a string to this (should avoid any snags to the propellers
