"The policy journey of São Paulo, Brazil, a vast metropolitan region of 20 million people, has been telling. The city council initially banned all ride-hailing services via apps, spurred on by allies of the taxi industry. Other parties, recognizing the inevitable popularity of Uber as well as two more homegrown companies, 99 and Easy Taxi, pushed back. The compromise allows the companies to operate, but charges them for the use of streets per mile. A sliding scale was established—more if in the city center during peak hours with only one passenger; less for more passengers, cars in underserved areas, electric vehicles, women drivers, and accessible vehicles. A standing committee meets regularly on whether the charge needs to be modified. In the process, the city gets some raw data that can help with mobility policy.
The charges—for the privilege of using a public asset, the roadways, for commercial purposes—are estimated to bring in $50 million per year. Nearly a year after the policy was set, the experiment is going well, said Ciro Biderman"
