Excerpt:  
     Let the car along the road perpendicular to the direction of free air travel (on the left side, right in front of the vehicle or beyond), so that side of the roof of the car along the road to fly to the freedom of driving posture, so that car in the road surface, vertical path, Roof surface of the road between the freedom of driving, and that is what the invention of (freedom of movement in space on three sides and the space plane of the road system) can do.  
 
    The invention of the freedom of movement is a machine similar to the self-propelled vehicle of the campaign machinery, can be a common ground on the roads of two-dimensional mechanical movement (similar to the car), is in a specific two-dimensional track Two-dimensional moving wheel-rail campaign machinery. When it's in a particular two-dimensional running track, is a gravity and friction can not be both the physical conditions of the self-propelled mechanical movement, that is, in a vertical path, the road tilted, and can fly in the posture Roof surface of the freedom of traveling on the road.  
 
    The invention of the space of the road system is a two-dimensional path (of a certain width of the road, to allow freedom of movement for more than two machines staggered through the cross-roads) to build the road system; to a horizontal, vertical, The direction of the roof surface of the road link consisting of the road system; is a multiple-plane, a number of levels, a number of vertical plane with each other on the road (mainly constituted by the two-dimensional track on the road) to link up with each other, constitute a With three-dimensional features, with three-dimensional structure of the network space of the road system.  
 
    The invention of (freedom of movement in space on three sides and its road system in space) by building a three-dimensional space transportation delivery systems, may be the development of the city (including the construction of the structure of the city's development patterns, and even the structure of urban development patterns) have Significant and far-reaching impact.

Qu'est ce qu'il bave lui?  
Vas y on est en France la moindre des choses c'est de parler notre langue...
C'est comme si je parlais français sur les forums anglais ou espagnols
