South Australia is set to host the Southern Hemisphere’s first on-road test of driverless cars in November and independent road research group ARRB’s managing director, Gerard Waldron, says it’s just the tip of the iceberg. “We have six other trials at various stages of preparation for next year and a number of those will be in other states,” Mr Waldron told The Australian. South Australia introduced a new piece of legislation late last month that allows testing of driverless vehicles on state roads by exempting them from selected existing laws, in a bid to attract car manufacturers and technology companies that are pouring money into driverless cars.
