Google are doing this as well. And yes I would be happy to trust 'auto driving' I would use it often but not always I enjoy driving myself.
The possibilities are wide reaching.
Auto driving would be great when you are tired, in particular if you are driving long distance, let the car drive and you can have a nap.
Imagine being able to to phone your car and ask it to come and pick you up.
Imagine taking the car to the airport and instead of paying for the car park your car could drive itself home.
Or having a drink at the pub and letting your car drive you home instead of sitting in a sick filled minicab.
Ultimately it will be safer the radar can see everything all around it. Your eyes can only see straight ahead. Its the future people.
