In my mind structured road conditions are a prerequisite for driverless cars.

I've been in many situations where conservative driving according to the rules of the road is not possible. In the West this is more limited to dense cities and exceptional situations. In India, though, this is the rule.

If you waited for pedestrians to finish crossing or for cars to clear intersections, maintained a safe following distance, signaled before turning, waited for other parties to yield, etc, you would never leave your driveway.

It's difficult for me to imagine a computer deciding to gently nudge pedestrians with its bumper in order to proceed through a green light, which I've had to do several times while driving there.
