I don't think we've ever played Commie Crescent, which might be interesting. The winner is the first to redistribute Mornington Crescent to all the other players.

BM] Your example of driving in New Zealand illustrates my point. Of course there is a practical advantage to carrying your driving license whilst driving. This practical advantage is that if stopped by the Police, you would nat have to go through the painful process that may arise from your not carrying it. This is my point with ID cards - one might carry it purely for teh "practical" reason that it is law and it is easier just to obey the lwa and thereby avoid any ridiculous consequences that may arise from not carrying it. But there is no MORAL reason why one should carry an ID card. I think what you fail to realise is that although our moral obligations often comply with legal obligations, many people do not believe that something is a moral obligation simply because it is a legal obligation. This is especially true when it comes to minor traffic violations. I must say that I find your blind obedience quite frightening, in a 1984 kind of way.

StD] I know this is an argument where no-one will convince anyone else, but I have a problem with individuals deciding what they are and are not morally obliged to do. I'm sure Harold Shipman believed that he was morally right in relieving these old people of their suffering (and I know that's a reductio ad absurdum, but it is the other end of the same continuum). As for minor traffic offences, the roads are provided and maintained by highway authorities/the government for people to use in cars under certain conditions. Thus I would equate asking people to carry their licence with insisting that cars should be taxed and insisting on speed limits with insisting on insurance or insisting that people should not be under the influence.
On identity cards I would take the French view, that they should be provided cheaply and for all, but that it should not be obligatory to carry one (most French people do, but that's for convenience). However, the government shouldn't argue that they will be good for the country and for security and then try to recoup the entire cost of providing them in their cost.

[INJ] Individuals do make their own moral decisions, Shipman included. If you're suggesting a moral principle that laws ought to be obeyed, that's your principle and you're welcome to live by it, but it's still up to everyone else whether they decide to adopt that principle or not.

[INJ] "Cheap" identity cards? Whatever the upfront fee, the entire cost of introducing cards will be borne by the taxpayers. That is where governments get their money from.
