@kezo It operates the same way as the BMW system, just with added bings and bongs 😂 If traffic is bad, and it calculates that an alternative route is quicker, it sends you on the quicker route.
Bings and Bings aside, it’s actually a better system than the BMW one. During journeys, even when there are no traffic issues, it will often show alternative routes in grey at various stages, along with stats like “2 miles shorter, 5 minutes longer”.
One thing that I really like is that in variable speed limit stretches on motorways it keeps a running total of your average speed through that section.
