As seat belts were not commonly used at that time, the person could easily fall out of the car and into traffic, hence the name "suicide door".
[1] Rear-hinged doors were common on cars manufactured in the first half of the 20th century,[1] including the iconic Citroën Traction Avant.
[7] The French, hand-made Facel Vega Excellence offered a four-door hardtop with a Chrysler-sourced Hemi V8 beginning in 1954.
Other luxury models with rear-hinged doors include the Spyker D8 and the Rolls-Royce Phantom Drophead Coupe four-seat convertible.
The most recent mass-produced model with such doors may be the Opel Meriva,[8] followed by the Rolls-Royce Cullinan in 2018, and a few Chinese electric vehicles including the Singulato iS6 in 2018 and HiPhi X in 2020.
[12] Rear passenger rear-hinged doors had long been used on Austin FX4 London taxis, discontinued on their successors the TX1, TXII and TX4, but reintroduced in the 2018 LEVC TX.
[13] Other car manufacturers which have produced models with suicide doors include Citroën, Lancia, Opel, Panhard, Rover, Saab, Saturn, Škoda, Studebaker, Ferrari, Mazda and Volkswagen.
