Can you give me an executive summary of the 260 answers your post has generated? Is it YES or NO?

To be fair, 250 odd of them have been about public transport in the
Cambridge area including a level of name calling and a discussion on
metallurgy.

That arose from a discussion of the second of the OP's questions (which,
incidentally, doesn't have a Yes/No answer):

"Has anyone used Uber? How does it work? What is the service like?"
