These articles also never mention how this is going to work in the fabric of a city.

Say optimistically a 15 second separation between vehicles, 4 passengers per vehicle, means one ¨sky-lane¨ can transport 60/15 * 60 * 4 => about 1000 people per lane. That´s worse than a car lane, and an order of magnitude behind bicycle lanes and subways. You can stack multiple lanes vertically, but then it becomes more fun with traffic control for take-off and landing and still a bicycle lane transports more people.

So far these things seem better as a city hopper, or used in a rural setting, but the current ones don´t have the range for that either.
