I couldn't believe how rough and run down the NYC subway system was when I visited. At least they have a somewhat adequate number of lines and what not, compared to somewhere like Toronto which has probably 1/6 the size of a subway network a city of its population and wealth should have. Hard to say what is worse.
I figured that the richest city on earth would have good public transport. When I visited for the first time I was shocked to find that there was no aircon, no cell reception, and rats fucking on the platform.
This is effective infrastructure use. Instead of having to run cell service or wifi in the tunnels just so people can browse porn on their phones, they bring the smut directly to you.
