Do I need to add in delay times to calculate total travel time with Google Maps?

Yes, when calculating total travel time with google Maps, it's advisable to consider potential delays such as traffic conditions, roadwork, or weather-related issues. google Maps typically provides an estimated travel time based on current conditions, but adding buffer time can help account for unexpected delays. If you're traveling during peak hours or to a location with known congestion, it's wise to factor in additional time.
