I see comments like this quite often without any suggestions for how it would happen practically.

Rethink taxation so people living in suburbs pay proportionately to the cost of running services to them, and you'd very quickly see a denser city. Dense habitation is just way more efficient, more ecologically friendly, and more cost effective. If this was reflected in the law, you'd very quickly get a situation like you have in Germany, where you basically go from multi-storey apartments to farmland with no suburbs…

Ha! I wonder which parts of Germany you mean? The cities I've lived in, the cities I know, and the city I live in now are not like that at all.

Can I have 30? I need to get to my hyperloop pod faster. Those modern transportation 'solutions' are a sign of local maxima of current city design. A bad design that cannot scale any further. So maybe instead we start on fixing cities?

Lots of US cities used to have great public transit. They were all later 'fixed' to remove public transit and make life easier for cars.

I often see (without hearing) helicopters in the downtown brooklyn area. If this aircraft flies above ~600 feet, noise should be little to no concern.

You need to live in a quieter area. Too much noise pollution in NYC. In a suburb of Portland Oregon I routinely hear helicopters up to about 2000 feet. I hear many planes at over 5000 ft. When jets take off from PDX and climb over my house I can easily hear them at about 16,000 feet. https://globe.adsbexchange.com

Depending on the weather I hear aircrafts at 32,000 to 40,000 ft. Trough closed windows (double paned isolating stuff) at night. Mostly traffic from/to Paris, France and from/to Asia, which goes over here.

There will be a difference between a hovering helicopter and one travelling at cruising speed. I assume you experience more of the latter while I the former.

Leipzig has a pretty sharp divide, for example. If you walk west, you hit platenbau, then it's a bunch of farms. I figured a lot of east cities are like this (Gera, for instance, Halle, etc). It could be a matter of perspective - in London, you can drive for about an hour through suburbs before you see a single building more than two stories.

Hm. Could be. Never been in those parts, so far. My experience is much of Rhine-Ruhr Area and then 'the North', mostly Hamburg, sometimes the less crazy parts of Berlin ;-)

Yeah, definitely the rhine-ruhr area has some suburbs, but it's still way more dense than the UK. I get the feeling there's a big divide between west and east basically because of ideology: in the west, the state encouraged women to stay at home (no free kindergartens, tax-splitting between married couples, etc). This in itself makes a house with a garden way more attractive - if you're stuck at home looking after kids, then it's really nice to be able to do stuff in the kitchen while your kids play in the garden. They also had way higher car ownership. There's also stuff like building law (you can generally only build stuff that fits in the locale, so there's more space for potential suburban houses than apartment blocks) which I guess wouldn't be a factor in the east. Also high car ownership, (obviously) higher rates of house ownership, etc.

And for some reason the "solutions" always have the nice feature that they get those using them out of the sight of the rest of the lowly peasants living in those cities.

And with driverless cars around the corner, now is the time to integrate them correctly. The idea should not be to get in your Tesla at home and cruise on the highway and into the city to park at your office. They idea should be picked up at your house by an Auto that drops you at the lightrail station just in time to catch the next train into downtown, where you can hop in a 10 person driverless shuttle that drops y…

The advantages to self driving cars being used this way are even better:

- people driving don't have to take time to find parking lots

- the cars themselves don't need to be parked in the city, freeing up space

- depending on how many people are traveling together and what they are transporting different sized vehicles can be used

That being said: the most efficient form of transportation any human can do right now is the bicycle. It is fast too. During rush hour I am faster than car, bus or subway on my commute (German city) and as I am sitting on the computer for long periods anyways, having a little movement is great. And for weather there is appropriate clothings.
