I think that motorists should stop tailgating generally – and bicycles specifically – and give us a bit more room.
Frankly I’m getting a bit **** off…
Buses with “Cyclists stay back” WTF? Roads are a shared resource.
“S/he wasn’t wearing a helmet” – relevance?
High Viz for cyclists? – when cars are dark blue, grey, black, dark green, brown.
If you want to invent something, that’s great, a good exercise.
BTW night riding. Agree with poster above, there is little more distracting than a rear light. I’ve done a bit of night racing, rear lights are really distracting and annoying. FFS you can see the beam cast by the front light. You’re in the flow, you know when someone’s going to stop, because that’s where you would stop.
