guide-rail copter traffic

copters fly along a "road" with no intersections

An elevated rail is used only for guiding these copters between cities, and perhaps pulling them forward but the extremely lightweight wire is not used to hold the vehicles up, so the infrastructure is extremely low cost, and allows for very high- speed traffic.

Use this instead of high speed trains or airplanes.

Aerial Trolleys Vernon's similar idea. but not LTA [pashute, May 21 2019]

Tethered Aircraft PRT Similar but not personal and without switches [pashute, May 21 2019]

High Speed train Chinese style https://www.travelc...-trains/high-speed/
China has thousands of these miles of TGV lines. Miles of high speed lines in China = 18,000. Miles of high speed lines in USA = 0 miles. Both are totally astounding achievements in their own ways. [xenzag, May 21 2019, last modified May 22 2019]

       In places like France, Japan and China, TGV trains travel faster than any helicopter. In the USA, high speed travel via anything but aircraft is totally unknown.

       Rotorcraft are intrinsically limited in speed by the advancing/retreating blade asymmetry. They are also complex and grossly energy-inefficient.   

       There are motorbikes that can outpace the majority of helicopters.

       This idea would make slightly more sense if, instead of using "copters", it used towed, winged gliders.

       //co// with, //pter// wing. So the terminology does not rule out towed gliders.

       Tilting at copters are we. It has been done and they can be fast. As for tethers, they really have to pay in some special respect in this day and age of autonomy .
