"uh, yeah. Sort of WTF, isn't it? Silver ended thingy is a mirror. Yellow spiral seems to be connected to dangly green fluoro light. Check out the homemade handlebar grips - plus an orange & black button at the end of handlebar."

"Yeah, padlocked to the carrier. While looking this over I started wondering how long it takes to remove/secure the various bits. I suspect there's a pannier that goes with the cyclist, and contains some electrnics that normally go in a bag on…"

Richard D replied to David's discussion What the Minister of Transport will do for you
"A lack of joined up thinking when it comes to cycling infrastructure? Surely not. If only there was somebody in charge of making sure that this sort of thing didn't happen. Like perhaps a government minister in charge of all forms of transport,…"

The paper, the online appendix, videos, and the companion historical study are at:…
