I think it is more a question that here in the UK, the vast majority of drivers have absolutely no consideration for anyone else on the road and treat driving as a pain in the arse that needs to be done as quickly as possible and with the least amount of disruption to their own life. This is why we see so many of them texting, phoning, reading meeting notes etc.
Part of the problem in my opinion is that we keep making laws that are not or can't be enforced, hogging middle lane, handheld phones etc, so people think they can get away with anything.
