The reality of driverlerss cars on UK roads is closer than you might think. The technology required for cars to drive themselves in simple scenarios has already been used. Self-parking, lane-centering, adaptive cruise control and automatic braking are already common features of mid-priced vehicles. But most of the barriers to adoption are down to people’s perceptions of how autonomous digital vehicles might respond to the analogue unpredictability of the real world.The rewards of implementing this technology could be huge, not only by improving air quality and congestion, but also because it offers individuals who can’t drive—including some people with disabilities—access to independent personal transport. This is why Bristol is exploring some of these new ideas.
