Electric helicopters come with the advantage that they’re much simpler to maintain surely.

Go watch some of these and tell me you trust these people to maintain an EVTOL vehicle, however simple.

We already have fatal car crashes from people who neglect maintenance and don't get their car inspected. Now imagine instead of a 2D plane to cause a wreck, on a road where people are generally alert and paying attention for wrecks, they can fall out of the sky onto kids playing in yards, onto busy roads out of the sun, or just onto each other during the final approach/take-off.

Nope, air travel is only safe because we strictly regulate pilots and maintenance.
