With Uber, you already get a picture of the driver, along with the plate number, make, and model of the car. You also already necessarily have a device capable of calling 911 by using Uber (your own phone).

This whole idea that Toronto (or London, or Quebec) is the only place in the world with the unique insight to regulate ride sharing services with their own unique snowflake policies needs to be dispelled. Many of these regulations (including the ones you're citing) clearly are relics of the past that don't reasonably apply to these services.

Residents of Toronto won't be able to move forward by clinging to the entrenched status quo out of misplaced beliefs that their regulations are future-proof, infallible, or provide any significant amount of additional safety to riders.
