In a mini-review [Physica A {\bf 392} (2013) 5261--5282] it has been shownthat classical traffic flow theories and models failed to explain empiricaltraffic breakdown -- a phase transition from metastable free flow tosynchronized flow at highway bottlenecks. The main objective of thismini-review is to study the consequence of this failure of classicaltraffic-flow theories for an analysis of empirical stochastic highway capacityas well as for the effect of automatic driving vehicles and cooperative drivingon traffic flow. To reach this goal, we show a deep connection between theunderstanding of empirical stochastic highway capacity and a reliable analysisof automatic driving vehicles in traffic flow. With the use of simulations inthe framework of three-phase traffic theory, a probabilistic analysis of theeffect of automatic driving vehicles on a mixture traffic flow consisting of arandom distribution of automatic driving and manual driving vehicles has beenmade. We have found that the parameters of automatic driving vehicles caneither decrease or increase the probability of traffic breakdown. The increasein the probability of traffic breakdown, i.e., the deterioration of theperformance of the traffic system can occur already at a small percentage(about 5$\%$) of automatic driving vehicles. The increase in the probability oftraffic breakdown through automatic driving vehicles can be realized, even ifany platoon of automatic driving vehicles satisfies condition for stringstability.
