Autonomous cars will be their dream.
You will not own a vehicle. You will have a subscription.
When you need a vehicle, you call for one similar to an Uber.
You tell them what you need (pickup for hauling, just a ride, or a minivan for the whole family).
Vehicle shows up, collects you and takes you to your destination. There will be no steering wheel.
All vehicles will speak with each other and the infrastructure (traffic lights, road signs, etc) and traffic will flow smoothly.
Of course, they will know your movements every step of the way....but they know that now if you carry your mobile phone with you.
I think we will see that sooner than we think. Maybe metro areas first.
