Two things I have to wonder about:

1. Why do they think/feel they have to LOOK AT THE LIGHT that's approaching? Look a little to the side of it if you want to 'keep an eye' on the approaching whatever-it-is. Are they two-legged deer?

2. Why do people get so zoned out of their immediate surroundings, and when it did it become so acceptable? Example (other than cycling): while at work today, three of us were waiting for the coffeemaker to finish. One lady turned her back, the first guy in line tried to get her attention to let her know she could just stick her cup into the dripping stream and get her cup faster... but she was suddenly unreachable, as the TV had captured her. No response to his repeated calls to her.
