I have a route which I have taken a couple of times using Google Maps navigation and every time I go it takes me one of 3 different ways, even though I start and finish with the same location every time.
In web Google Maps the directions returns 3 results which are 35mins, 40mins and 41mins with varying routes, one is using 3 motorways, another is motorway-town-motorway and the last is through the "backroads".
Is GNavigation making this decision intelligently (traffic reports, time of day etc) or randomly picking me a route of the 3 available? This is in the UK.
