One obvious example: CCTV everywhere, at least in London. Is that new?
Its been happening for a while. We are officially the most openly watched country in the world. It is perceived to reduce crime, and people don't mind it. Don't forget that there has been a serious terrorist threat in the UK for at least 35 years, and CCTV footage has been used in several successful terrorist trials lately.
I'd say that some of the orderliness that you get in the UK is merely cultural (like queuing for example), others is caused by the fact of our relatively crowded existence, as I said before (you can't avoid impacting on other people), some of the security stuff, like cctv and not allowing unattended luggage is a function of long-standing terrorist threats.
On the other hand, from a British point of view, US laws and punishments are generally seen to be too severe, particularly with respect to drinking alcohol and the relatively low speed limit. And our police are generally unarmed, and its quite normal to go up to a bobby on the beat and ask them what time it is, or for directions.
The biggest difference is that there seem to be more tribal identities (class / town / etc) in the UK and less emphasis on the individual. This is probably just a product of diverging histories (e.g. our early industrial revolution). Don't forget that we are culturally at least, an island of people who didn't
leave to seek our fortunes in the colonies.
