Ever since Google first rolled out it’s autonomous cars, the world has been watching their progress. The safe cars, free of human error are expected to revolutionize the way automobiles are used. Some studies expect them to become the norm in under a decade in cities in the US.

The town of Milton Keynes in the United Kingdom test drove the cars for a public transport system that will travel between the town’s train station, commercial, and business districts. The cars are likely to have place to seat two passengers comfortably with their shopping bags and even has place for a baby stroller.

The cars in Milton Keynes will use a special lane and move at just 12 mph. However they are the precursor for things to come. Soon towns all over the world will have similar systems set up to enhance public transportation.

Self driven or autonomous cars pose a serious challenge to law makers around the world. Should this vehicle which is essentially a machine that operates itself, be involved in an accident, who is to be liable for the damages that it causes?

These are the problems that will keep law makers busy for a while. Even as the different science projects on autonomous cars make progress across the world, these legal issues continue to muddy the waters.
