France is probing a spate of collisions that are being blamed on phantom braking after a car crashed on a motorway when it went from doing 65mph to a complete standstill.
The phenomenon is said to be behind a growing road safety hazard after a string of terrifying incidents in which cars have slammed on their brakes without warning.
One high-profile case involves Joanna Peyrache, who was driving her Peugeot 208 near Lyon when her car suddenly decelerated from around 65mph to a complete stop 'for no reason'.
The vehicle behind her crashed into the back of her car, causing major damage, though she escaped serious injury.
Neither her insurance company nor the other driver's insurer would assess the car, leaving her to investigate the problem herself, according to local reports.
