You're approaching an intersection. A child runs out. What happens next is up to technology

Driverless cars could make our roads safer and reduce congestion. But the algorithms driving them will also have to make life-or-death decisions. At some stage in the future, a fully autonomous car may determine who lives and who dies on our roads. These machines are being tested right now and Australian politicians are looking overseas for leadership, emboldened by the promise of fewer fatalities and less congestion. At the moment, there must be a human behind the wheel of these cars at all times, but government agencies are already working on a legal framework for when machines are totally in control.
