Bikes: Kids can operate it because it is simple to operate (i think)
Driverless cars: Simple. Just put in where you want to go and it takes you
Cars: Difficult with brakes gear accelerator and other stuff
Just a few examples
Will kids be able to use driverless cars like they can ride bike (on roads in Australia).
They won't need any skill (apart from using the navigation system) to use a driverless car.
