No, and please don't straw-man my argument. I contend that those who can avoid such risk ought to, because each pedestrian who does so has an increased risk of getting hit.
To analogize, I believe you ought to avoid unnecessary medical treatments, because each presents some kind of risk. If, however, you need treatment, I suggest you receive it (though it will carry a risk). By the same token, if you can walk carefully and observe the world around you, you ought to. If you need to walk and cannot see, it's fine to just accept that certain things carry risk.
Hearing is arguably more useful in many situations, as it is omnidirectional. I can hear a car coming from behind me; I likely cannot see it.
How much chance do you think you'd have of getting out of the way of an out-of-control car coming from behind that you couldn't see but you say that you'd hear?
