I too am very much of the opinion that life is a risk, I don't want to be wrapped up in cotton wool nor do I wish to put myself in unnecessary danger. But am fatalistic about what will be will be.
You do what you can (or are willing) to mitigate risks, the rest you accept.
I do tend to wear black (or dark/muted colours). My bike has lights and reflectors/reflective stips so I don't feel the need to wear more. I understand all the arguments but am free to choose. The same applies when snowboarding off piste, I understand the risks but I choose to do so.
After all I work in an office and my life isn't exactly the adrenaline fuelled adventure it used to be, some of us need a bit of risk to feel alive, all the arguments and consequences be damned.
I now only drive a car maybe once a week and am regularly surprised at the lack of skill and judgement of (probably) the majority of drivers. This is one instance where I would be happy for more regulation, re-tests every 5 years to include refreshers on the highway code.
The advice to drive appropriately for the situation is spot on but often something that will only come with experience.
So again you mitigate the risks of riding in traffic.
I assume everyone on the road has a basic level of competence (occasionally I do get proven wrong) but are all capable of stupidity. The hardest thing is to assume you yourself are also capable of surprising stupidity and to remember that before you do something stupid!
