What are you talking about? You don't witness an accident so it must not have happened? How illogical is that?
This morning on my way to work I was hit by a car, as she overtook me with oncoming traffic while I was overtaking a stationary bike (man putting his daughter on the child seat). She didn't have room for the maneuver but continued on anyway. The lady continued driving because she was in shock, I caught up with her and asked her WTF was she doing. Her response said it all "I didn't think ...bla bla bla". She didn't even know what to do in an accident. The traffic started moving again and she moved off.
Every day there are incidents on the trip to work.
Helmets, high viz gear and lights are essential. It's idiotic to venture out without.
Expensive lights and high viz clothing (gloves, bib & coat) couldn't prevent stupid people doing stupid things.
Sorry, I'm not following you. Are you saying hi-viz is essential or that it can't in fact "prevent stupid people doing stupid things"?
Were you wearing hi-viz when that motorist nearly hit you? Do you wear hi-viz every day on the trip to work?
If so, what difference is the hi-viz making in practical terms? Genuine question, by the way, not merely rhetorical.
