When you gain an editing area by driving, WME never tells you when it will be taken away. The only way to know is to remember the date of every trip you made, which is not realistic. In practice editors discover the loss after the fact, sometimes in the middle of handling a UR that can then no longer be closed.

The information already exists on Waze's side: those areas are derived from dated drives, and WME already shows that drive history to the editor in "My drives". What is missing is simply surfacing the resulting date.

What would help, in order of usefulness:
1. In the "Your areas" tab, show the expiry date (or a countdown) next to each driven area.
2. A warning when an area is about to expire, so that pending URs can be finished first.
3. Optionally, the same indication on the map for the area currently in view.

Worth noting: an editor cannot reliably work this out on their own. The drive history available in the editor is shorter than the validity period, and the area polygon is noticeably wider than the radius the editor announces, so any local estimate stays approximate. Only the server knows the real date.

This is not a new computation, only the surfacing of a value Waze already holds.
