Cab Co.

From Memory Alpha, the free Star Trek reference

Cab Co. was a taxicab company that operated in San Francisco, California, on Earth, during the late 20th century.

When the HMS Bounty went back in time to 1986, James T. Kirk was almost hit by a Cab Co. taxi. Kirk and the taxi driver shared a few colorful metaphors with each other before the taxi passed. (Star Trek IV: The Voyage Home)
