I use this. Got fed up with Google Maps (in navigation mode) constantly trying to get my attention for things unrelated to driving. "We've found a faster route!" it would say, as if saving five minutes on a five hour journey is the least bit useful. Either I take my eyes off the road, fumble for the button to say "ignore that option", then try to re-focus on what I was doing, or it just switches me across to the other route anyway. It would do this multiple times in the journey. The wego option just does navigation, no distractions or foolishness.
