Well, yes - but some reasons for that are the safety and regulatory systems in place to ensure that fail-safe designs are taken to market. For this type of air vehicle, those aren't too mature yet - but I bet it's coming.
It would be fascinating (but no doubt unlikely!) to get sight of the eHang safety case, and in particular how much power each motor demands in the hover (especially high DA - e.g. Dubai) and whether there is sufficient margin for control in the event of a motor failure throughout the intended flight envelope.
A fascinating job for some in the Dubai CAA, regardless.
