Recently we can and have seen a lot of movement on the race to automate our vehicles. This can be seen most readily in the recent introduction of cars which can break automatically through the use of sensors on the vehicle.
We can see this trend has been growing for years, and for good reason. Automatic vehicles would literally revolutionise the way we travel, and transport our goods. If all the cars and trucks on the world drove themselves, without any human input, we would see the abolishment of drivers licenses the world over. But we can see some more immediate effects right now. This automatic breaking mechanism is sure to reduce car crashes as soon as it is being heavily introduced in a majority of vehicles.
According to companies who are investing heavily in this technology, like Google, we will see these automated automotive vehicles quite soon, a lot sooner than you might expect anyway, perhaps even within the next two decades.
