You would have been on time, but you couldn't find parking. Sound familiar? To help you avoid these types of snafus, Google is adding a parking difficulty icon to its Maps app for Android, which indicates potential problems in metro areas.

Based on historical parking data for your destination, the Maps app populates a parking icon with either "easy", "medium" or "limited". Its purpose is to offer a more accurate representation of start-to-finish travel time than driving time only.

Sorry, small and mid-sized cities – for now, the feature is restricted to 25 major metropolitan areas in the US: San Francisco, Seattle, Miami, Atlanta, Boston, Charlotte, Chicago, Detroit, Los Angeles, Minneapolis/St. Paul, New York City, Orlando, Philadelphia, Pittsburgh, San Diego, St. Louis, Tampa, Washington, DC, Cleveland, Dallas/Fort Worth, Denver, Houston, Phoenix, Portland and Sacramento.

As of yet, Google has not indicated any plans to expand this feature to other regions or into Google Maps for iOS.
