Problem:
When starting navigation from a stationary position, Waze often assumes my car is facing the direction of the road segment, not my actual heading.
This leads to wrong initial instructions — for example, being told to “turn right” when in reality I need to make a U-turn first because I’m facing the opposite direction.

Proposed Solution:
Use the phone’s built-in compass and orientation sensors to estimate the initial heading of the vehicle when navigation begins.
In most real-world cases, the phone is positioned facing the same direction as the car (mounted on the dashboard or windshield).
By using this heading information, Waze could:

Determine the correct driving direction before movement begins.

Avoid confusing or incorrect first instructions.

Make navigation smoother and more intuitive, especially in parking lots or side streets.
