Why are evtols safer than helicopters for bystanders? They both have the spinny blady things.

Re noise, most of the sound comes from the rotors rather than the engine. It's not obvious to me that an evtol craft could significantly improve this.

There seems to be an assumption that evtol == multiple ducted fans. This isn't necessarily the case. And electric helicopter would be evtol. Any specific design is going to have different tradeoffs. Eg more motors to fail.
