And encourages friendly family discussions when getting lost. .
Not quite so sure about it always being friendly, when lost......the best bit about touring on the Harley (before they were fitted with sat navs) the helmet intercom system had a PTT switch, which over-rode the microphone of the passenger, proved very useful from time to time, the silent bliss that ensued whilst the better half vented their frustration. She found a work around which usually involved a repeatedly prodded finger in my shoulder or a not so gentle tapping of my helmet......but for a while that PTT was on occasion bliss.
