Latest updates… and still to come…


30 April 2021 – New information on day-riding lights – originally called for by a conference on road safety in Vienna in 1968, adopted by the European Motorcycle Manufacturers Association ACEM in 2001.

1 May 2021 – UK’s 2021 ‘Think Bike’ week still claiming that wearing hi-vis clothing and using day-riding lights will mean “drivers will see bikers”.


28 April 2021 – Science Of Being Seen delivered to 150 member of Thames Valley Advanced Motorcyclists


LIVE ZOOM PRESENTATIONS of the Science Of Being Seen

I created the Science Of Being Seen presentation in 2011/12 for Kent Fire and Rescue Service to be delivered as part of the free ‘Biker Down’ accident management and first aid course, and after Biker Down went national, many of the teams opted to use a version of SOBS with their course.

I personally delivered SOBS once a month for KFRS  from early 2012 until February 2020, when COVID-19 prevented us running the courses. KFRS have since decided as part of their COVID safety policy that all content shall be delivered in-house by their own staff for the foreseeable future.

But you can now book a seat for my new regular LIVE SOBS PRESENTATION to be delivered online!


And if you would like to organise a closed-to-club Zoom presentation for YOUR OWN RIDING CLUB OR GROUP, drop me a line and I’ll put wheels in motion.  


‘Looked Saw & Forgot’ 27 September 2019 – Crucial new understanding – ‘Micro-memory lapses’

The authors of a paper entitled: “The ‘Saw but Forgot’ error: A role for short-term memory failures in understanding junction crashes?” have proposed a mechanism by which some motorcycle collisions which are current classified as ‘looked but failed to see’ crashes are actually the result of a memory issue – the motorcycle is actually seen and brought to conscious attention – but is then somehow forgotten again in what I suggested might be termed a ‘micro-memory lapse’.

In computer terms, this is ‘FIFO’ memory – first in, first out – and the buffer size is small.

What this means from a practical point of view is that in an environment where there are few vehicles, and assuming that the bike is seen in the first place, drivers (and other bikers incidentally) WILL remember the PTW as they plan their manoeuvre, so factoring in the motorcycle.

But in a crowded environment, where there are many things to keep track of, there is a risk that a motorcycle, although it HAS been seen, is then forgotten as other vehicles and maybe cycles and pedestrians catch the driver’s attention. With many vehicles to keep track of, there is a risk that the motorcycle’s presence slips from this short term ‘micro-memory’ as it’s filled with newer data.

Although the paper went on to give the suggestion that drivers should ‘see bike, SAY “BIKE”‘ to engage a different pathway in the brain to prevent these memory issues, my own conclusion (once again) is that it is just another reason why motorcyclists should assume first and foremost that they have not been seen, and be ready to take evasive action.

I will be incorporating this new theory into SOBS at the earliest opportunity. In the meantime, there is a fuller explanation here

JUST ADDED / coming soon

Just added 17 April 2019 – each page now has a short summary at the top, which covers the main points set out in the rest of the text.

Coming soon – a brief explanation of what ‘science’ is, how it works, and whether we can trust the results.

Coming soon – some positive conclusions about how motorcyclists can prevent themselves being caught up in a ‘Two to Tangle’ collision with a driver at a junction.


Don’t forget – start from the bottom!

Since you’re here, I’ve a small favour to ask. If you feel able to make a small donation to the upkeep and continued development of SOBS, why not buy me a coffee? Each contribution is much appreciated. Each cuppa keeps me awake and writing! Thank you.
