ah, pedestrians, bless 'em.......... I had a strange encounter on my way to work one day. I was coming down a hil on my bike, fairly fast, and a pedestrian decided to cross the road without looking. I rang my bell, she looked up, froze, I swerved to go behind her.....then she skittered back to the pavement, so I had to swerve the other way. I had to laugh, she was obviously half-asleep. But I do think a lot of pedestrians rely on their ears rather than their eyes, and can't hear a bike coming. My bike now has rattles on to try to overcome this problem.
