Many, many years ago, I decided it would be a good idea to fit a beeper under the seat on my old 250, on the indicator circuit, to remind me to switch them off.
My then girlfriend, now present wife, took this as a cue helpfully to go 'Meep, meep' in my ear to tell me when a turn was coming up. This continued for decades, even when we were in a car.
The outcome has been that whatever part of my brain that serves one's sense of direction has shrunk, apparently irretrievably. I was once told by a guy who fought in the Balkan wars that I wouldn't last a day in urban fighting.
So I use Google maps all the time, but will never again have a beeper, or a clicker.
