Isn't there any public surface transportation in the city?

Nope. It was all banned about fifty years ago, on account of the congestion. Taxis and everything. You can still use a private car in some parts of the city, of course, but the only people who own them are those who like to impress their neighbors. Most of us take the Undertube or the Overshoot to get around.
