Why don't you believe that to be true? There are a myriad of ways for a combustion powered helicopter to fail. Just look at how many billionaires have been killed in helicopter flights.

Electric motors do not fail as often as combustion engines. Most eVTOL designs have redundancies that don't exist in a normal helicopter. I have flown R22s a handful of times and there were many times where an engine failure would have been disastrous.
