Where I live, to be a cab you need a commercial drivers license
Which is just a note that you have given the state extra money, of no actual value to anyone. Uber drivers have that though, just not UberX.

regular vehicle inspections
UberX also makes sure you have a vehicle in good shape before you can drive
a tax license

and are legally required to have a camera installed in your car.
Uber drivers are all tracked by GPS continuously and if they are smart have a camera in the car or voice recording app also. It's not magic.
