New York City is taking aim at a ride-sharing app that's been operating in the shadows. The city has filed a lawsuit against the unlicensed service, alleging that it's putting riders and drivers at risk by failing to follow basic safety and regulatory standards. The app, which has gained popularity among some New Yorkers, claims to offer cheaper fares and a more convenient experience than traditional ride-hailing services like Uber and Lyft. However, city officials say that the app's lack of oversight and regulation makes it a safety hazard, and they're seeking a court order to shut it down.
