They're upset over the lack of regulation on ride share services like Uber and Lyft. They claim without regulations, it puts not only people's safety at risk, but also their money.
"They don't need a chauffeur's license, they can charge whatever they want to, they can jack the price up when it rains, when it snow, or whenever they feel like it," said Michael Shakman, lead counsel, Miller, Shakman, & Beem.
The lawsuit comes a day after Mayor Rahm Emanuel proposed some rules on ride-sharing companies, like training for drivers and vehicle inspections.
The city says they'll look to have the lawsuit dismissed, claiming the plaintiffs' complaints have no merit.
