This is because Google Maps uses a combination of different data sources to provide users with information about sites, street view, satellite imagery, and user-contributed content. This means that if you have never visited a place physically, you may still be able to see it on Google Maps.

However, leaving the setting on for a prolonged time period will lead to Google Maps displaying a timeline that presents information about a person's daily movements. These findings establish the fact that “Google spying on you” has been confirmed by the researchers, according to an AP report.

Limited offline functionality: Google Maps requires an internet connection to function properly, making it less reliable in areas with poor or no internet coverage. Privacy concerns: Google Maps collects and stores data on users' locations and search history, raising privacy concerns for some users.

On average, a one-hour session using Google Maps in online mode can use up to 200MB of data — a significant amount if you're traveling and have a limited data plan.
