I was going to reply and say "You wouldn't see a cyclist riding down the road with headphones on, blissfully unaware of what's around them..." but then I thought back to my cycle commuting days and remembered a fair few examples of seeing just that. And anoher one in similar vein; the cyclist who swerves out into the road to avoid a puddle at the kerbside --without so much as a rearwards glance to see if any cars are coming up behind.

No. Pedestrians don't have a monopoly on obvlivion. But neither do cyclists. Some of the things I saw people doing behind the wheel of their cars or lorries, as I cycled past them would put you off going out on a bike for life.
