> Most cities require you to show ID to use internet.

Complete nonsense; aside from cities in the UK not having any powers to control a thing like that (they are no way near as devolved as big cities in the US, for example) there is no legal obligation to provide ID to access the internet. I think you might be referring to a recent proposal to legislate online activity through access cards; but that was a proposal that has no backing at the moment.

You technically don't even need to have your licence on you when driving (though you can be required to show it within 7 days).
