> Google Maps shows you the most efficient route Not always. I live a little bit northeast of a city, and when I have to work south of the city, Google always gives me a route through town on lower speed roads with traffic lights. I usually take a different route with no stops and higher speeds and save about 10 minutes and a splash of fuel.
