It's not the ID. It's the massive joined-up database they wanted to put behind it so that a policeman stopping you can access your DWP records and NHS records, and local authority records and criminal records and anything else the state holds on you.
That was the problem last time.
Also remember that the UK is incapable of any large project (Universal Credit, anyone) and when things go wrong, it's nobodies fault.
Remember, I work in IT. And admittedly you'd have to kill me before I worked in local government, however living in Brum and having this happen in slow motion before my eyes has been psychically painful as I know I wouldn't even get an interview.
