I live in the EU and thus I can travel pretty far away without having to ever show my ID card. Maybe it’s just personal experience but whenever I had to show it, no-one cared about it wasn’t valid anymore.
Another trick is acting stupid: “Oh, thank you! I didn’t notice! When would a normal person check that, eh? 🙂 … Right on next Monday I’ll going to renew it!” and then hasta la vista, we won’t meet ever again anyways.
The next time I have to renew it, is in 2031. I guess I won’t renew it till 2040.
