UK roads are plagued with potholes currently. Receiving warnings about them is very helpful - but reporting them is a real fiddle! It involves hitting the 'Report' baloon, then 'Hazard', then 'On road', and finally 'Pothole'.
No-one should be juggling all that while driving, and yet RECEIVING the warnings is most helpful. Nor can you go back and mark them later. There are too many!
If the problem isn't such a major issue elsewhere could it just be introduced in the UK?
