Supernal designed a flying car with bees and it is quiet and designed to work

Supernal, a US-based company that wants to replace noisy helicopter and regional plane with all-electric, multi-rotor vehicles, unveiled its electric vertical takeoff and landing prototype at the CES 2020. Supernal said its aircraft will operate as quietly as a dishwasher. The S-A2 will emit 65 decibels in vertical takeoff and landing phases and 45 decibels while cruising horizontally, it added.
