Google Maps is testing new features that will enhance user experience by providing real-time updates on parking availability, fuel-efficient routes, and estimated time of arrival (ETA) directly from the initial overview screen after entering a destination. Currently, users can only see traffic conditions, distance, and travel time. The new features will allow users to view parking availability marked by a "P" icon, fuel-efficient route options, and precise ETA. These enhancements aim to improve trip planning and are expected to be included in future app updates. Additionally, some users have reported issues with their Timeline history disappearing from the web version, possibly due to a shift in how Google stores location history.
