A law against drunk driving finally came into force a little over half a year ago but hasn't really changed anything. Everyone still drives around completely out of their tree.
If there is such a thing as a São Paulo bus map, I still haven't been able to find it. Asking people can help, although often even the drivers and cobradores don't know where they're going.
Bus stops are always located in the middle of blocks and well away from train and metro stations, rather than at corners of the crossings of main roads and rail routes.
Passengers in Metrô and train stations always stand on the escalators and never stand on one side to allow people who want to walk up to pass. Further, if there is a ludicrously crowded escalator, and a completely empty set of normal stairs, everyone will still try to pack onto the escalator. These people love escalators.
Morning and evening rush hours see traffic on main routes, in ten lanes and three layers (including elevated and underground), going absolutely nowhere.
