If you want to be able to fly around like this at low altitude, why not just get a powered paraglider? Cheaper, safer, longer flight time and you can buy one today?
"There is some talk of having two jetpacks on top of every skyscraper in China."
Sure, you could have a near-experimental jetpack which requires significant training to fly safely and which costs a quarter of a million dollars, or you could spend $2,500 on a standard airplane emergency parachute which any random bozo can use safely with about three minutes of "here's how you buckle the straps, and here's the ring you pull."
Same basic thing for a these weird hybrid car/airplane contraptions they call "flying cars." For less money you can buy a great car, a great airplane, another great car for your most frequently visited destination, and have enough money left over for rental cars for all your other destinations for the rest of your life.
Now I just have to fight my wife about it, who'd rather have a small SUV...
I would argue that there would be very few people with zero parachute experience that with just three minutes training could jump from a building and not die catastrophically at the bottom.
Then there are only two rules to learn: 1) keep your feet together and 2) keep your legs 'semi flexed'.
And if you forget the rules then you usually break an ankle not 'die catastrophically'.
Guys that go base jumping off buildings have years of practice, and they're aware of how risky it is doing a low altitude jump around objects.
It's interesting that hovering, VTOL and small size are only important at the beginning and end of your flight. Maybe there's room for some kind of hybrid that takes off and lands like a small compact flyboard, but unfolds wings while cruising for better fuel efficiency? No idea how that would look though.
Probably a lot like a powered parachute. :-)
The jet pack gives you VTOL, 100 miles per hour, and probably the wind is less of an issue (albeit not a non-issue).
