Suzie says "So I am going to prove it to you, OK? Are you ready, because here it is: "And then fails to prove anything except "Now, excuse me, I might not be an economics expert,". 

I have no doubt that adding 116 cabs will through a monkey wrench into the finances of most cab drivers. It will reduce the available revenue of the 188 cabs by about 40%. It won't change the cost because the cost is already determined by the Muni. When you get into a cab and the flag drops the regulated charge starts and each mile has another regulated charge. So more cabs will not reduce any charges to the consumer. It will just split what money is out there more ways. 

The ONLY way to reduce the cost of cabs is to re-regulate it. Let Uber and Lyft operate and tell cabbies they can charge what they want. The market will find a center and go from there.
