Robot drivers

http://www.northamptonchron.co.uk/news/Baths-closed-and-traffic-lights.4555083.jp When the lights were out of action, says the report, "Motorists had to be careful", implying that when lights are "working", they don't have to be (as) careful. Paradoxical but true. Lights remove responsibility for decision-making. They turn us into robots, programmed to act according to switchgear, not innate intelligence or the needs of the moment. But when we have to keep our wits about us, we are more likely to do the right thing.
