I have presented you with evidence that it works all over Europe.
Integrated public transport reduces traffic, pollution, money spent on expensive alternatives like cars and taxis...
How do I get to the airport nowadays? By taxi! Just like in Lagos! Third world attitute I say.
I recommend you go and leave your comfortable armchair for a while, travel to places like Hamburg, Rome, Copenhagen, Amsterdam and so on and look how it can be done.
The integrated public transport systems there are
clean comfortable affordable relieved of social stigma.
It is pointless to discuss any further, you are riding the 'privatise everything' argument without grasping that privatisation means profit for shareholders, not best service for customers. Comfort, cleanliness, affordability and social integration are not on the agenda of a private company, it is simply maximising profit...wrong when it comes to poeple wanting to get from A to B.
