My pet peev are texters while walking, especially in busy pedestrian areas. I'll play devil's advocate, I see it like this, if you are too pre-occupied by who's looking at your farcebook page, then you deserve what you get when out in the public domain, be it falling over, hitting a lamp post or getting splattered by a bus, Darwin. You have it coming to you. We I ride my bike (as probably all of you too) I'm all too aware of my vulnerability and so am on constant alert mode, why as a pedestrian should you not take the same precaution, unless you are out in a field, then watch out for fire ants.
