The benefit is crossing the street at all tbh. And yeah, I consider giving enough warning to the drivers to be important. I don't stand in a crowd, and I make sure that there's enough space that the driver will be able to comfortably stop when I'm already in the street.

But if you're driving in the city, you really do have to be careful. Drivers are at the bottom of the legal totem pole because we have so much potential to harm everyone else and are more nimble than trucks and busses.
