London: Car giant Ford has developed revolutionary new ‘wi-fi’ brake lights that warn other drivers to slow down to avoid a rear-end shunt – even when they can’t see why.
It knows when cars that are out of sight around a blind corner – or  even hidden in traffic in front of a large bus or van -– are hitting the brakes and warns the drivers behind to do likewise to avoid a crash. Ford has been using  specially-equipped Ford S-MAX models to test the technologies.
When the car in front brakes it sends a wireless or ‘wi-fi’  signal from its illuminated brake light to any other cars behind which have the same system, giving those drivers a warning on their dashboard saying: ‘Caution! braking vehicle.’–MO
