Every time I go to a particular destination, Google Maps tell me to exit the freeway early and take backroads. Everytime I ignore that exit and stay on the freeway a little longer, my estimated travel time reduces. Yes Google, please continue sending me on the backroads which would cause me to get there later, thanks.
Didn't you notice Google Maps is turning into a social network? You can follow and message businesses, see photos taken in certain locations. It has nothing to do with navigation and reducing travel times anymore.
