Propellers are exposed rotating blades, and no ducts or protections are used on them... To say nothing of rotors, that sometimes cut heads and arms...Hi folks..
OSHA and NTSB will have something to say about exposed rotating blades...
Even at 10 feet, ducts will be needed, add weight, but it will be necessary.

Times have changed... Today, people are squeamish and risk-averse... Not so in 1914...Rebuttal...
1. The Flying car cannot be considered an aircraft it it cannot get above 10 feet. It would be a slaughter if it were used on today's roads.
2. If the intent of staying low is to use current roadways, the NTSB and OSHA will have something to say about it.
3. If it is supposed to be a "Jetson" vehicle, then I would agree with your assessment of and only if the altitudes travelled were at aircraft altitudes and routes helicopters would use.
But that current proof of concept vehicle is not ready for prime time just yet. Along with other limitations seen thus far it is a nice toy to play with until the craft can get above the current height limitation.
I would still want ducting to protect ground support personnel on this craft particularly. "Clear prop" may not be enough warning.Just my $.02
None whatsoever.What are the chances this will be affordable to the commoners.
Looks impressive until the fine print reveals there is no pilot on board , let alone the 5 passengers it claims to hold , so what we have so far is an oversize drone which recently burned in an electrical fire .What are the chances this will be affordable to the commoners.
