Computes the vehicle's safe speed (no dawdling) This method is used during the insertion stage. Whereas the method followSpeed returns the desired speed which may be lower than the safe speed, this method only considers safety constraints.
Returns the velocity of the vehicle in dependence to the vehicle's and its leader's values and the distance between them.
