Agreed - a "least hassle" route would be better.

Google maps has sent me on some really werid routes with endless turns left, right right left right right right left left right left etc etc vs just staying on a main road with only one or two turns for only an extra couple of minutes minutes more

I'd be more than happy to stay on the easy main roads and turn once or twice rather than hack through the backstreets just to save <5% distance/time
