If pedestrians don't take what's theirs (in a safe manner), there are just far too many drivers who will ignore them. Fixing that will take decades, best case, but I want to walk around my neighbourhood as a first-class citizen now. So I do.
Disclaimer: I am tall, visible, only do this in good visibility, and live in Canada where driver behaviour is a bit better. If the situation is borderline, I never tempt fate, rather I throw my hands up in the air and make it obvious that yes, I hereby assert that this driver is being an asshole.
