A 17-year-old died in front of her dad when the locks and handbrake of their car were triggered automatically, sending it flying downhill.
Aaliyah Sedley-Jones, known as Lily, was sat alone waiting in the family vehicle when she decided to start the engine "for an unknown" reason, disengaging the automatic handbrake, an inquest heard.
Desperate efforts to open the doors and stop the Citroen rolling away by her father Benjamin Jones were thwarted as he watched in horror as it locked automatically due to its speed and flipped over, the BBC reports.
