It would be a gross disservice to assume in reality that anyone RUB or otherwise might NOT respond as these riders did.
Being a good citizen is not contingent upon ones degree of experience riding a motorcycle. Nor is ones degree of relative tendency to be a good samaritan if a situation calls for it.
It certainly is not contingent upon what brand of anything we drive, ride or play with.
Truth be told we probably all know some RUBS who are very nice people ...even if they only ride their shiny chromed Harleys on the weekend.
