Hi,

I can see what you were trying to do with this edit, but the tag motor_vehicle=designated means that it is designated for ALL motor vehicles. Think of the designated access value as being like yes, but stronger. For example, public footpaths are generally tagged designation=public_footpath + foot=designated.

The previous tagging of access=private + bus=yes means that buses may always use this road, but other transport modes, like TfL tow trucks and Newham street cleaning vehicles may only do so with explicit permission. It might make more sense to change it to access=private + bus=designated
