I often switch on GPS on mute mode when driving a road I know, but not it's surroundings. Then when a road block appears I do not need to think where to go, which side to take when the road suddenly splits etc. I needed to use that maybe 3 times in my life but it was great to know that I can make mistakes which will be corrected by the GPS
