I leave it to you to decide which is worse; needing an I.D.card just to hire a locker at a water park or being able to circumvent the security/bureaucracy with a car park swipe card with my photo on? Ardent supporters of I.D. Cards will excuse the former by saying that the Spanish will have their cards with them in their wallets anyway. The same cannot be said for tourists I didn't anticipate needing my passport to do my best impression of a walrus on a waterslide. I happened to have my swipecard in my wallet.
Isn't this another example of why the introduction of identity cards in the UK would be an expensive and futile exercise. Now where is that suncream?
