I can't comment whether we, as a whole (society? the world?), are too accepting of distracted driving. The enacting of more "distracted driving"-style laws would seem to indicate we (at least in some areas) are becoming less tolerant of distracted driving.
What I am saying is you can't blame a cyclist for being angry that they were almost smeared across the pavement because a driver was texting or just plain being stupid. I would say that the OP is too accepting of distracted/inattentive driving, not because he let the driver go without getting angry, but because getting angry at an inattentive driver is apparently akin to a cowboy getting angry with the bull that bucked him off. If everyone had that attitude (specifically drivers) the roads would be far more dangerous than they are now.
