His intention, in choosing his supposed bon mot, was presumably to impugn the masculinity of the cyclists. He seems to have been unaware that it takes a good deal more grit and effort to push yourself round town on a bicycle than it does to drive round town in a fast car - and it is a good deal more socially and environmentally responsible as well.
And, if he had cared to make those same remarks to the same people while on foot, rather than from the safety of his car, he might have found his own manhood subjected to a rather unwelcome and daunting challenge.
But the real question is, why does a young man of Max Key's age and upbringing think it appropriate, not only to shout insults at strangers but to refer to women in such demeaning terms? What is it about our society that spawns such offensive attitudes? It seems clear that the expensive schools responsible for the education of young Mr Key and his like have some way to go in preparing their pupils for adult membership of a decent and equal society.
Even his father acknowledged that Max Key's remarks were "inappropriate" - probably the mildest word he could find to express his true feelings. It is certainly depressing to think that we might be bringing up a whole new generation of Donald Trumps.
As Trump himself demonstrates, those who cross the boundaries of decent behaviour in these respects seem blissfully unaware of how damaging is their lack of respect for that half of humanity that produces their wives, mothers and daughters. And they seem not to know that the "locker-room talk" that they regard as so natural, normal and common to all red-blooded (or, in Max Key's terms "real") men is a piece of pathetic macho posturing abjured by most decent men.
We are not short of evidence of the damage that is done by such attitudes. The high incidence of domestic violence and of sexual assaults, and instances such as the boastful exploits of the so-called roastbusters, are bad enough, but they take no account of the psychological damage that is suffered in our society by so many girls and women who find themselves treated without respect, and as sex objects and pieces of property rather than as people.
We have no chance of achieving a society in which women are treated with proper respect and can take their full and proper place for as long as a Max Key can hurl such a thoughtless and offensive comment at strangers and expect to be applauded for it.
I can, on the basis of long experience, offer a tip that might help Max Key in his search for what it means to be a "real" man. If you treat your female friends and partners as real people, you will be part of a stronger society, your relationships will improve - and you will have a better understanding of the joys that your "love life" can offer.
