*User Story*
As a user, I want to see the ETA of the driver, so I know how long I need to wait.
*Acceptance Criteria*
Immediate booking
1. On user's screen, there is [x]min displayed (similar to Uber).
2. That ETA is updated when the driver is moving.
3. When the driver arrives to the drop-off and press on button, we stop tracking.
Scheduled booking
1. If the driver doesn't open the app, we cannot track (or can we?)
2. If the driver opens the booking, we can track.
3. When the driver arrives to the drop-off and press on button, we stop tracking.
