Which bit of the above is in your opinion 'tripe', Mustafa - your bit, my bit or Themas' bit? You tend to have a habit of making initial assertions on these legal questions, then not coming back later to clarify your answer.
The bit that is 'tripe' (to use your phrase) is the idea that a private road has no legal owner - it's possible on a really old development that has grown up over time on a lane (non-highway) but unlikely on a 1950s development. IMHO it is most likely that the ownership of the road was carved up into pieces, or the original development builder still has ownership (if done by a single developer).
