The signs on the top of their vehicles also read “limousine."

Tobias said he sees the city as using the recent crimes as a means to gain an advantage and try to regulate these companies that are already monitored by the state.

“Interesting that the only driver charged was a Blue Cab driver — (a) driver and company licensed under the city taxicab ordinances," Tobias said.

He added that the city officials and the taxicab board may be heeding pressure from taxicab companies to enforce regulations on companies like Green Cab because they find it hard to compete.

“If these local taxicab companies want to compete with our service then they need to turn in their used police cruisers … and get some polite, uniformed drivers,” Tobias said. “We’ve raised the bar in Ann Arbor … and nobody’s happy about it.”
