Instead of working on a useless driverless-car, why couldn't Google work on something useful?
If they can create a driverless car, why can't Google:
-Detect whether an 80 year old grandmother at the airport has a bomb on her.
-Detect when a woman is getting paid less than a man for the same work.
-Detect when your child is being molested or bullied.
-Detect when you are getting spam.
-Detect when Google Chrome is going to crash.
-Detect when your retirement fund is going to become worthless.
-Detect when your identity has been stolen.
Google could be spending its time, and your money, doing something useful.
