Both parties did not knowingly agree to the terms. From the article, quoting the office of NY Attorney General Letitia James:
> From 2014 to 2017, Uber deducted sales taxes and Black Car Fund fees from drivers’ payments when those taxes and fees should have been paid by passengers. Uber misrepresented the deductions made to drivers’ pay in their terms of service, telling drivers that Uber would only deduct its commission from the drivers’ fare, and that drivers were “entitled to charge [the passenger] for any tolls, taxes or fees incurred,” though no method to do this was ever provided via the Uber Driver app.
