Zeppelin isn't safe, slow and not effective for mass passenger transport. Zeppelin can't hold many people in big city scale and/or short hop. Did you know how many passenger that can loaded on?

I prefer metro.

Recent article on Airship used for sightseeing :

Compare the volume of the Zeppelin vs the number of passenger. If I remember correctly, it only take 7 passengers and it is rather slow to land and take off. So you have a lot of wasted time.

This really does not scale well when talking about big conurbations with millions of people.
