I know my way to work very well, but I can take 3 main routes which all roughly take the same amount of time but have many more little alternative tweaks. The traffic can vary so massively from day to day, a 35 minute journey on a Wednesday could easily be a 60 minute journey on a Thursday, just 'because'. So, I ALWAYS set a route to work to show traffic conditions and then use my own knowledge of country lanes to pick the best option based on where traffic is worst.
Apple Maps showing an over-view of the whole journey that auto zooms in to the map as the journey progresses is ideal. I don't need turn by turn, just traffic indications.
So, anything which does this is a good thing.
