That's easily dealt with. It's a legal obligation under the Road Traffic act to produce your licence when asked for it by a Gardai. Pass a simple amendment to the act to remove the 10 days presentation piece and impound the car until a licence is produced. People will learn very quickly to carry it.
Exactly; as happens in Germany (and probably many other European countries). Isn't it strange that our competent (sic) lawmakers failed to include such a provision in the first place?
