I don't have much experience of the free alternatives (Waze, Google Maps etc.) but mobile phone TomTom (via CarPlay) has never let me down - and often helpfully guided me to avoid traffic problems. After using Google Maps occasionally I am always relieved to get back to TomTom because it prunes out so much you don't need - to achieve clarity for what you do - and certainly for an over 70 year brain the annual cost (I think £19.99 or £29.99 for Iphone family multiple use) is well worth it: whilst my wife and I use the years (and remaining good health) left to us to max out on Schengen.
Their use of 'Danger Zones' is a clever work around, I was not aware of that, perhaps it is a recent change, thank you
