This is pretty interesting. I did close to what this guy's neighbor did without the chat part. Pulled up to the neighborhood corner, looked both ways, and absolutely did not see the guy on a motorcycle(J on his Harley) until I had already started to cross the intersection. Still feel bad about it even though it wasn't even close.
