From Chas Bazeley
Teal Burrell gives a fascinating insight into the way the brain copes with forming habits (16 January, p 30). Observing my own and other drivers' behaviour on UK roads, I note that many appear to be on autopilot when driving at steady speed.
But if the routine is disrupted, for instance by a child running into the road, how long does it take to engage a different area of the brain and react?
