User Problem: When driving long distances, I want to visually see my current progress between two set break points so I can better plan rest stops and manage fatigue.
User Story: As a driver, I want to set a break interval (e.g., every 100 or 200 km), and see a ruler or progress indicator on my navigation map that shows:

Where I am now
How far I’ve traveled since my last break
How much distance remains until the next suggested break

Feature Details:
Setting Behavior
Break Interval | Select from predefined (e.g. 50, 100, 200 km)
Visual Indicator | A horizontal or vertical ruler-like bar showing trip progress and break markers
Map Overlay Option | Optional mini-ruler overlay on live map view
Notification Alert | Optional sound or pop-up when nearing break point (e.g., “You’ve traveled 180 km – time to plan a break”)

How It Works (Example):
You set a trip from Point A to Point B (500 km)

You select: “Break every 200 km”

The app draws a ruler with segments: 0 → 200 → 400 → 500 km

Your current location appears as a moving marker along this ruler

When you pass 200 km, a gentle alert reminds you to consider stopping

Benefits:
Helps manage fatigue during long trips

Reduces guesswork for break timing

Encourages safe driving habits

Useful for families, truck drivers, and road trippers
