   “Some Londoners have a death wish. Every day I slam on the bike brakes to avoid ploughing into people blissfully unaware of traffic thanks to their iPods ... Podestrians, as they've been labeled, wander blindly into moving traffic, smiling happily to Neil diamond.”

   “Because he was listening to his iPod, he didn’t hear the approaching light aircraft as it made an emergency landing … Two thoughts strike me about this unfortunate incident. The first is that I can see how it might have happened. “Podestrians”, as they are known to the emergency services, now account for one in 10 of all minor accidents involving the sudden braking of cars or bikes.”
