I eagerly look forward to the implications this tech has. Imagine homes built without garages because you just summon a car when you need it. Being networked to all the other vehicles and smart roads it will be able to safely whisk you to your destination in comfort - no road rage, no ego, no road hogging, no drunk driving, no hoonin, no crashes and possibly even no stopping at traffic lights because the road will tell the vehicle what speed to be at to ensure a journey that doesn't get a red light.
instead of purchasing a vehicle and forking out for fuel, maintenance, license and registration, etc you just pay a set monthly fee as you do with water, power, gas, phone, internet, etc or pay as you go much like we do now with taxis and uber.
These vehicles are electrically powered and when they need to recharge they just head for a recharge point and plug themselves in so no more visits to the gas station.
Because these vehicles will be summoned when you need them this may also mean fewer parking spaces will be required and you'll never need to worry about finding a parking spot and paying for it or getting a parking fine - imagine that!
The future is exciting.
