An auto-driving car is a great idea. It helps people who does not have a good skill in driving to have a safe journey by their own car. If your are tired from your work and want to have some some rest or worried you slept while you are driving and you can turn on auto-driving, isn’t it help enough. It may save other people live too!
This car is not just a regular Prius. It is a Prius with a lot of sensor, camera and connected to satellite and Google data center.

It is not a perfect system yet… but for starting it is a great technology!
