An Oxford University startup, Oxbotica, proposes to solve the problem of liability in a collision involving autonomous vehicles by allowing insurers access to the vast amounts of data the car generates, even allowing them to control a car in real time if it detects a dangerous situation. A recent paper published in Transportation Research found that autonomous cars could bring about the end of congestion with no obvious explanation. These are caused by one driver's unexpected behaviour (most often braking) being copied and exaggerated by following vehicles. The study demonstrated the networked cars were able to slow more gently and not create jams. A recent study published in Nature from Google-backed AI company Deepmind claims to have developed an AI program that resembles the neural GPS system found inside the brain.
