Oxford UK has many new 'Low Traffic Neighbourhoods' which involve many side road closures. These have not been included in your maps and so many people are attempting routes proposed by their TomTom software and then having to reverse out in narrow spaces and retrace their steps. This isn't efficient. I have asked Oxfordshire County Council if they can liaise with you on this. The lack of accurate detail on the current TomTom map is causing widespread chaos to many classes of vehicle using it.
