If They Need Air Traffic Control, They Are Also Going To Have Accidents

Drones. There will also be noise pollution. No?

Air Traffic Control for Drones

7,500 unmanned craft weighing 55 pounds (25 kilograms) or less will be operating in the U.S. by 2018. There is strong interest from agriculture, mining, and infrastructure companies in using drones for tasks like inspecting crops or gathering geospatial data .... gridlock in the skies, or at least increasingly unsafe traffic patterns. ...... If a drone strayed out of its approved area, for example, the system might automatically send a command that made it return to its assigned area, or land immediately. ..... Airware believes that equipping drones with cellular data connections could be the best option. The equipment that conventional aircraft use to communicate or send digital data to air traffic control systems is too bulky for use on drones. ..... Giving drones relatively free reign below an altitude of a few hundred feet, except in the vicinity of airports, would mostly remove conflict between drones and general aviation

Cities That "Feel" European

Well, considering I have never been to Europe (where a lot of Bollywood movies are set).

Urban "Fingerprints" Finally Reveal the Similarities (and Differences) Between American and European Cities

Travel to any European city and the likelihood is that it will look and feel substantially different to modern American cities such as Los Angeles, San Diego, or Miami. ..... New York and Tokyo share similar shape distributions but the visual similarity between these cities’ layouts is far from obvious. ..... cities fall into four main types ... The first category contains only one city, Buenos Aires in Argentina, which is entirely different from every other city in the database. Its blocks are all medium-size squares and regular rectangles. .... An example from the second group is Athens in Greece. These cities are composed mostly of small blocks with a broad distribution of shapes. ..... Most cities that Louf and Barthelemy studied fall into the third group. Like the second group, the blocks in the cities have a broad distribution of shapes. However, they tend to be larger than the blocks in Athens. ..... This third group contains several subgroups. One of these contains 68 percent of all the American cities that Louf and Barthelemy studied. By contrast, all of the European cities, except Athens, fall into another subgroup. This “European” subgroup also contains Boston, Washington, Portland, Pittsburgh, Cincinnati, and Baltimore, which have a European flavor. ..... There is one final group, represented by Mogadishu in Somalia, made up almost entirely of small square-shaped blocks with a sprinkling of small rectangles..... It may also allow other kinds of “city science.” An interesting approach might be to look for correlations between crime and certain types of neighborhood layout.
