Single-file vs Double-file and the Curious Case of DFROC

The people who run Australian media outlets love stories that can be framed as “drivers vs cyclists”, and a real beauty has just dropped in their laps. It’s an online petition calling for double-file cycling to be outlawed. This is currently legal, despite many people believing otherwise.

The Project on DFROC
One of the better treatments of the issue was from The Project. Click to watch their segment.

The cycling social media world is up in arms and some are even trying to shut the petition down on the grounds that it’s “endangering lives” or even that it’s hate speech.

Where you stand on this issue depends on one question – is it safe for drivers to overtake people on bikes in the same lane? The answer to that essentially comes down to how wide things are. Can a bike, a car, a 1 metre gap between them, and some margin for error all round fit within a lane

How wide are these things? Let’s start from the left of the lane, and move right:

WidthThing
0.5 mWhen riding a bike you need a buffer from edge of road/left lane in case of debris, potholes, or just to give room for a slight wobble.
0.6 mWidth of my bike
1.0 mMinumum mandatory passing distance been driver and bike (it’s 1.5 m for roads with a speed limit over 60kmh
0.5 mDrivers need a margin for error to ensure they maintain the minimum 1 m gap (which is not quite wide enough anyway)
1.9 mWidth of 2018 Holden Commodore. Some cars are narrower, but then buses and trucks are much wider.
4.5 mTotal

And guess what? The standard urban lane width in Australia is 3.5 metres. It’s often narrower, particularly in inner-Sydney where I live, and particularly on main arterials where widths of 2.7 – 2.9 metres are common.

The upshot is that drivers need to change lanes to overtake people on bikes, whether single- or double-file. But single-file riders are roughly double the overtaking distance of double-file riders. Be careful what you wish for DFROC.

Single-file vs Double-file

Like so much of the “popular” reaction to cycling issues in Australia, this petition isn’t based on practicality. It simply an attack by one group against another they perceive to be less powerful than them.

The curious case of DFROC

The petition appears to originate from a Facebook page called “Drivers for Registration of Cyclists”, which until about a year ago was a satire page filled with cleverly faked news articles showing moronic motorists becoming bewildered as they were faced with the negative implications of their own demand for registering cyclists.

And then about a year ago the page abruptly did a 180, and became filled with cleverly faked photos showing cyclists doing supposedly “wrong things”, mixed with strident demands for “single file please”. It was hard to understand. Were we all being subjected to an elaborate, but obscure experiment in manipulating our assumptions and our emotions? The Photoshop fakery style before the switch was identical to that after the switch, suggesting that if it wasn’t the same author it was somebody who had closely studied their style and had the skills to copy it exactly.

An example of the "new" DFROC
The “new” DFROC showing their competent Photoshop skills, cutting and pasting riders from one part of the road into another.

It was weird. After a few weeks of it I unsubscribed, dumping it in the “unsolved mysteries” department in my mind.

The petition has brought the mystery of “Drivers for Registration of Cyclists” (or DFROC as they’re known by cyclists) into the limelight. The general consensus is that it is the work of an Australian sports cyclist named Ivan Vetsich, but some believe it is connected to a man named Ivan who lives in Ireland. Are there two Ivans? Did Australian Ivan move to Ireland and become Irish Ivan? If he did, why is he still banging on about Australian cyclists and trying to get the Australian law changed?

Mysteries…

    Twelve-year olds are banned from riding on the footpath, so must ride on the road. Sara from Sydney rides double-file to protect her 12-year old from overtaking traffic. I do the same with my eight-year old when we ride on the road, which is often necessary where I live due to the lack of footpaths.

    There’s evidence to suggest it is both. I’ve seen screenshots of Irish Ivan discussing being asked to administrate by Aussie Ivan.

  3. Ivan is a dick looking for glory.

  4. Unbelievable the hate levelled at most vbije riders. Road deaths cost Australia $32billion last year and obesity $36 billion and some car drivers at getting uppity about people exercising.

  5. Thanks for this, Colin.

    Great read…Particularly interesting the fact that single file requires more length for a car to overtake. I had not though of that before. Thanks Colin.

    Its a 1.5m gap at over 60km/h, not at over 80km/h isn’t it?

      Yes, you are right, and I’ve edited the post to make it clearer. I had written it as “1.5m for 80kmh or more”, which was kinda true, but ignored out those rare 70kmh zones.

  8. Ha! I’ve been riding Beach Road for 25 years and I’ve never seen cyclists ride like in the pic. Who rides like this?… no-one.

  9. Where is the photoshop? Looks genuine to me, all the bikes/ riders shadows are there. Why the hate?

    • That photo is on beach road Melbourne. During a sanctioned triathlon race. The roads are closed. Have a look on the other side of the road where the witches hats are. Notice there are no cars in sight…

    • Its a triathlon race where Beach Rd is closed off. Notice the witches hats on the other side of the road? I race at these events. the roads are closed. Notice any cars in sight?
