No, they do not.
The safety and cleanliness of public infrastructure ultimately stem from the culture of the people living there.
My wife tried using the bus system for her first six months working in downtown LA, but ultimately gave up because she was getting harassed regularly. I stopped using the metro after a rider on my train walked up and down the train threatening to stab everyone and nothing was done about it.

It’s a vicious cycle and the only ones who profit are the car companies.
