Chinese scientists have helped create a new safety system for automated driving systems that can sometimes react to hazards more quickly than the human brain. The slower reaction time of machines compared with the human brain has been a long-standing safety concern. For example, an automated vehicle travelling at 80km/h (50mph) will take half a second to respond to a hazard in front of it, compared with the 0.15 seconds the human brain needs to react – meaning the vehicle will have travelled...
