Maybe we should all try reading the Highway Code. Rule 66 - 'never ride more than two abreast, and ride in single file on narrow or busy roads and when riding round bends.' As ever, what is required from both car driver and cyclist (and incidentally pedestrians...) is the ability to THINK and adapt to the conditions around them . Was the road busy or narrow? If the car was close enough to touch, this suggests that it might have been. Sadly, the ability to think is what is missing from most road users skillbase these days.

Marty,
The Highway Code contains some driving law,indicated by the words "You Must", and some driving advice indicated by "You Should".
Rule 66 is ADVISORY on riding in single file on narrow or busy roads,and therefore,these cyclists were NOT committing any offence.
Evelyn Smith on the other hand probably was committing an offence.Pulling alongside the cyclists to "Yell" at them,thus hesitating in her overtaking manouvre to do so,is driving without due care and attention(to the oncoming traffic AND the cyclists).
The fact that the cyclists were close enough to touch says nothing about the width of the road,only that the driver was overtaking too close to the cyclists.
I repeat that it is perfectly legal to ride two abreast and in this situation,these cyclists obviously felt a need to do so, probably for their own safety.
A cyclist has several reasons for riding two abreast,such as making themselves more visible to following motorists,and to cause those motorists to think for a moment and treat them as they would a slow moving car or tractor i.e to wait until the road provided a clear,straight stretch which made it safe to overtake.
Would it have been easier to overtake a long line of four cyclists in single file? Possibly, but it would also have encouraged less experienced or considerate motorists to try and overtake at innopportune moments, and if the driver then saw oncoming traffic, to pull back in,possibly colliding with the cyclists as they were now in a longer formation.This would be yet another fatal statistic on our roads.
As I say, cyclists have several good reasons for riding two abreast, whereas motorists only have one reason for wanting cyclists in single file,namely to shave a minute or two off their journey.Tell me what is more important, a cyclists life or a couple of minutes off a car journey?
So Evelyns Very Important Journey was delayed slightly.So what?
On todays roads, sometimes we all have to wait occassionally.
I cycle to work every day, but I also drive a car,and when approaching cyclists to overtake them, my thought is NOT "How annoying,I'm going to be a minute later than planned".
My thought is this,"If those cyclists were members of my own family, how much patience and room would I give them?".
The facts are that cyclists are ALL someones Mum,Dad,Brother,Sist
er,Son or Daughter, just like you.
The facts are that human life is more valuable than ANY car journey.
The facts are that SOME motorists need to think about this, and give cyclists more patience and room.
