Quite frequently I spot other cyclists initially by their shape and position, only later discerning the pitfully weak blink of a substandard light somewhere to their rear. Differences between human-made electronic photosensitive devices and the powerful combination of the retina and visual cortex notwithstanding, EBC ought to try the same thing with their stoogeclists against a street-like background of lots of different still and moving lights.
I popped out yesterday afternoon to retrieve my bike from the office car park after leaving it there over the weekend, unfortunately forgetting all my lights except those attached to my helmet - a ½W Cherry Bomb and one of those rubbery Revolution USB things. This may have contributed to the two dooring attempts along the Cowgate.
Vaguely relatedly, I had to drive from southern Glasgow to Ayr on Sunday morning which involved several instances of driving up a slight slope with the sun directly ahead a couple of degrees above the shiny-damp road in front. It was still possible to spot cyclists on the road, contrary to the reported legal pleas of murderers.
