Setting your Zumo to shortest distance without any avoidances might cause big problems in areas like ours. Here in the Alps such settings will have you riding down farm tracks, going through every town and village and following goat tracks up mountains. Now this may be what you want but most people would prefer the better roads and getting somewhere.
A good example would be staying with
us in Maltatal and going to ride the Grossglockner. From our door to the southern toll both takes most people around 90 mins. That's 90 mins of fabulous riding, down the valley to Gmünd, B99 south, local roads to avoid the town of Spittal then pick up the B106 before turning onto the B107 that leads directly onto the 'Glockner itself. Set your Zumo to shortest distance and you will have a very different experience. It will take about 3 hours because the "shortest" route involves narrow roads that pass through every village you can imagine and will end up on very rough tracks joining the B107 just before the toll booth. If you intend to ride the Grossglockner and then continue in a loop back here the shortest route/no avoidances settings will have you putting your bike in the train to get through the mountains to Mallnitz.
I find what works here, and I know it might not work elsewhere, is to set the device to fastest time then set avoidances to avoid motorways but not toll roads, avoid ferries (the train is seen as a ferry) and to avoid unmade roads. That way you will ride the best roads and actually get somewhere.
