Bek phrases American society's insistence on cyclist FRAP as being necessary to allow safe and easy overtaking by motorists. That is, American society assumes that cyclists cannot understand traffic operations and hence must be given childish instructions that suit motorists. Or, American society assumes that cyclist FRAP must be done because it always allows safe and easy overtaking. Well, that's what motorists think, because they have never had to seriously consider the facts; it was just easier and more agreeable to insist that cyclists do what motorists want. And that is precisely the line of arguments that Bek has been presenting.
However, it has long been recognized that lanes need to be atypically wide, 14 feet or more (depending on speed of traffic) for it to be safe for a motorist operating at normal running speed (not in slow traffic) to overtake a cyclist. With sufficient width of lane, then a cyclist operating FRAP can allow safe overtaking within that lane. If the lane is of standard or lesser width, as is typical, then the motorist overtaking a cyclist, even a cyclist operating FRAP, cannot do so safely without intruding into the adjacent lane. By other laws, that motorist may not intrude into that adjacent lane unless there is no traffic in that lane approaching so close as to constitute a danger. If there is no such traffic, then the overtaking motorist might as well "Change lanes to overtake!", in which case the lateral position of the cyclist has no bearing on the opportunity to overtake. That opportunity is entirely determined by the traffic in the adjacent lane, the sight distance, and such, regardless of the cyclist's lateral position in his lane.
That is the engineering insight which should be considered when discussing cyclist lateral position. Furthermore, it is the position strenuously advocated by Bek as an exception to the cyclist-FRAP laws, that is when he is not refusing to admit it without the cyclist-FRAP laws.
In short, Bek is arguing the motorists' arguments about the necessity of universal cyclist-FRAP and its bikeways implementation even though he is known to know the truth.
