@Nick-Carthew I don’t want to let that go unchallenged.
Complication:
First of all, I can’t see what would be so complicated about using a ‘block button’.
Apocalyptic Szenario:
The problems on German motorways and roads have become significantly worse in recent years (I’ve been riding a motorbike for exactly 50 years myself). In any case, these sudden road closures are no longer the absolute exception.
General benefit:
The app contains some features that aren’t relevant to ME, but I recognise that other users value them. If you don’t need help with diversions, be grateful for your sense of direction.
As I’m unfortunately not blessed with one, I use a Navdevice and would be grateful for any further technical support to get me back on track to my destination.
Or as we say say in Germany: "Haben ist besser als brauchen!" ("to have is better than to need")
