Uber and Lyft are pushing back against a New York City effort to regulate app-based ride-hailing services.
The city's Taxi and Limousine Commission says the new rules being debated Thursday are minor adjustments to existing regulations.
Commission Chairwoman Meera Joshi said at a public hearing that the panel's goal is safety, accountability and car availability.
The proposed rule changes would address fares, the availability of wheelchair-accessible cars and restrictions on picking up passengers at airports.
San Francisco-based Uber and Lyft say the regulations would discourage innovation.
Michael Allegretti of Uber said the rules would be "crushing" to Uber's New York drivers.
A few dozen Uber drivers chanted "We love Uber!" outside the commission's Manhattan headquarters before the hearing.
