Officials in California have been discussing how to legally integrate hi-tech driverless cars on its roads.
The Golden State's Department of Motor Vehicles must decide how best to go about this over the coming months. It follows a law passed in 2012 that set a deadline to have certified legislation in place by the end of this year.
The latest talks are focused on how the vehicles will record actions so the data can be used to reconstruct an accident in an effort to trace the cause.
Privacy is another matter which needs to be considered as members of the public may show hostility towards the driverless cars, assuming they are being used to collect personal data - while there is also the issue of accidents and responsibility involved.
In the case of the latter, the Californian DMV needs to decide whether or not the owner of the driverless cars get points on their licence.
A number of other precautions also need to be in place to protect the average motorist from the complications involved when interacting with such vehicles. It could therefore be some time before road officials in the state come up with a plan of action.
