> Why would a human driver be driving an automated car?

Because Google cannot legally operate the car in the streets without a driver. Therefore they put a driver there and it's on him to choose how to drive the car.

> What is the security mechanisms that allow such cars to be in the streets?

The wonderful security mechanism of liability, lawsuits, and insurance.

How many times in that 160K miles were accidents prevented by vigilant human override?
