To be honest, I hadn't really thought of the wider implications of self driving cars before:
Sergey Brin, a co-founder of Google, predicts that driverless cars will be ready for sale to customers within five years. That may be optimistic, but the prototypes that Google already uses to ferry its staff (and a recent visitor from The Economist) along Californian freeways are impressive. Google is seeking to offer the world a driverless car built from scratch, but it is more likely to evolve, and be accepted by drivers, in stages.Impressive.
As sensors and assisted-driving software demonstrate their ability to cut accidents, regulators will move to make them compulsory for all new cars. Insurers are already pressing motorists to accept black boxes that measure how carefully they drive: these will provide a mass of data which is likely to show that putting the car on autopilot is often safer than driving it. Computers never drive drunk or while texting.
If and when cars go completely driverless—for those who want this—the benefits will be enormous. Google gave a taste by putting a blind man in a prototype and filming him being driven off to buy takeaway tacos. Huge numbers of elderly and disabled people could regain their personal mobility. The young will not have to pay crippling motor insurance, because their reckless hands and feet will no longer touch the wheel or the accelerator. The colossal toll of deaths and injuries from road accidents—1.2m killed a year worldwide, and 2m hospital visits a year in America alone—should tumble down, along with the costs to health systems and insurers.
