  • Interesting fact: From 1836 to 1896, the Red Flag Act in England required that any self-propelled vehicle be preceded by a man carrying a red flag by day and a red lantern by night. In effect, this limited the speed to four miles per hour and retarded the development of all self-propelled vehicles, including the automobile.
    • propel To drive forward; move or cause to move on; urge or press onward by force.

In science:

Systems of self propelling particles (SPP) are widely represented in the nature.
Collective Behavior of Self Propelling Particles with Kinematic Constraints; The relation between the discrete and the continuous description
Numerous attempts have been made to find a model describing the collective behavior of self propelling particles.
Collective Behavior of Self Propelling Particles with Kinematic Constraints; The relation between the discrete and the continuous description
The first class consists of the models which are usually based on the analogy with the Navier-Stokes equation, where terms describing the self propelling nature of the system are added.
Collective Behavior of Self Propelling Particles with Kinematic Constraints; The relation between the discrete and the continuous description
In their work the collective behavior of self propelling particles with respect to a change of the density and the strength of the noise was investigated.
Collective Behavior of Self Propelling Particles with Kinematic Constraints; The relation between the discrete and the continuous description
The ordered motion of self propelling particles in is described by the CVA rule, according to which at each discrete time step (labeled by n) the ith particle adjusts the direction of its velocity vi (n) to the direction of the average velocity ui (n) in its neighborhood.
Collective Behavior of Self Propelling Particles with Kinematic Constraints; The relation between the discrete and the continuous description
It is therefore also a contribution which is in the formulation of the problem assumed to be cancelled by the self propelling force.
