Drove from north of Manchester to Stafford on a busy M6 return after Christmas and it seemed pretty accurate on telling me where the traffic was. A comparison with google and Waze at the same time suggested that not giving an alternative route was due to no alternative route rather than it failing. Im not 100% sure it’s being smart yet but at least when I can see the traffic on the map, I have a better chance of proving it one way or the other.
