On my way home last night I took the cycle way along Canning Street in Carlton. I spotted a bunch of people, in two separate groups, standing around wearing orange reflective safety vests.
I could not contain my curiosity, so I bailed one of them up and asked what they were up to. Turns out they were "conducting a light test for Ride On magazine."
I told her that I expect that I'd just failed the test then (given that the batteries in my front light were by this stage utterly flattened). Apparently they were not testing commuter traffic, but a set of commercial products.
