Lyft has declined negotiations with the commission; Uber has had discussions with area leaders.

But those discussions had been stymied by a change proposed by the taxi commission that would mandate Uber and any other car service advertising luxury vehicles for hire to charge a minimum fare of $25.

The taxi commission, which includes traditional cabdrivers and cab company owners, regulates for-hire vehicles in St. Louis and St. Louis County. Its members are appointed by St. Louis Mayor Francis Slay and County Executive Charlie Dooley.

Slay has supported the idea of bringing Uber’s black service into St. Louis.

“Now that the MTC has changed its regulations for Uber, it is up to Uber to identify new or existing companies to start delivering the service for St. Louisans,” Slay said in a statement.

But Uber maintains it won’t do anything until the $25 minimum is off the table.

Basil Rudawsky, a commission member who is president of the St. Louis County Cab Company, opposed most of the changes aimed to accommodate Uber’s luxury service.
