There is maybe a small benefit but I feel it is making the rider feel responsible for other people's failings. Also reinforcing the car drivers view that a motorcyclist is hard to see, yeah, people don't see my fkin truck at work, that's 50ft long 8ft wide and 15ft high, painted bright red.
The cars are far too capable and far too safe perversely. That makes us, as a species ignore the dangers as the likelihood of actually getting hurt is in reality quite low (on a caveman survivability scale in our psych), add a society that now sees everything as 'not my fault'. People cut corners brake too late etc. They are expecting the gaps to be there.
I think 90% of accidents are ignorant person versus ignorant person. They both expect the other to react to them in a deferential way and when they don't, bang!
To take it full circle (sorry waffling), as a rider you have to anticipate and react to the modern motorist, but your not responsible for their failings. Wearing a whizzy jacket? up to you, but 'chocolate teapot' springs to mind.
