Rapport sur la sécurité des véhicules Tesla

Chez Tesla, nous pensons que la technologie peut contribuer à améliorer la sécurité. C'est pourquoi les véhicules Tesla sont conçus pour être les plus sûrs au monde. Nous pensons que la combinaison unique de sécurité passive, de sécurité active et d'assistance conducteur automatisée est essentielle pour assurer la sécurité non seulement des conducteurs et des passagers de Tesla, mais aussi de tous les conducteurs sur la route. Cette vision est à la base de toutes les décisions que nous prenons, de la conception de nos véhicules aux logiciels que nous introduisons, en passant par les fonctionnalités que nous offrons à chaque propriétaire de Tesla.

Les Model S, Model X et Model 3 bénéficient du plus faible risque de blessure total parmi tous les véhicules testés par le programme d'évaluation des nouveaux modèles de véhicules nord-américain (NCAP, New Car Assessment Program). Ce résultat est dû en grande partie à la structure rigide fortifiée du bloc batterie monté sur le plancher du véhicule, qui confère à ce denier une résistance exceptionnelle, des zones de déformation très larges et un centre de gravité exceptionnellement bas. En raison de leur solidité, les blocs batterie de Tesla subissent rarement des dommages importants en cas d'accident. Pour finir, dans l'éventualité extrêmement improbable d'un incendie, la conception ultramoderne de nos blocs batterie garantit que le système de sécurité fonctionne comme prévu, isolant le feu de certaines zones de la batterie tout en évacuant simultanément la chaleur de l'habitacle et du véhicule.

Bien qu'aucun véhicule ne soit capable de prévenir tous les accidents, nous travaillons tous les jours pour essayer de diminuer l'éventualité qu'ils se produisent. Les fonctionnalités de sécurité actives sont proposées de série sur tous les véhicules Tesla fabriqués après septembre 2014, pour plus de sécurité au-delà de la structure physique de chaque véhicule. Comme chaque véhicule Tesla est connecté, nous sommes en mesure d'utiliser les données réelles relatives aux milliards de kilomètres parcourus de notre flotte mondiale (dont plus de 1 milliard parcourus avec la fonction Autopilot activée) pour comprendre les différentes façons dont les accidents surviennent. Nous développons ensuite des fonctionnalités qui peuvent aider les conducteurs de Tesla à limiter, voire à éviter les accidents. Grâce aux mises à jour logicielles à distance, nous sommes en mesure d'ajouter des fonctionnalités et des améliorations de sécurité bien après la livraison d'un véhicule, mais aussi de publier des versions mises à jour des fonctionnalités de sécurité existantes, qui tiennent compte des données réelles les plus récentes recueillies par notre flotte.

En octobre 2018, nous avons commencé à publier des données trimestrielles sur la sécurité, afin d'informer le public sur la sûreté de nos véhicules. En juillet 2019, nous avons décidé de publier également des données mises à jour annuellement sur les incendies de véhicules. Le nombre d'accidents qui concernent l'ensemble des véhicules en circulation peut varier d'un trimestre à l'autre et être affecté par la saison (lumière du jour réduite et conditions météorologiques défavorables, par exemple).

Accident Data

Q2 2021

In the 2nd quarter, we recorded one crash for every 4.41 million miles driven in which drivers were using Autopilot technology (Autosteer and active safety features). For drivers who were not using Autopilot technology (no Autosteer and active safety features), we recorded one crash for every 1.2 million miles driven. By comparison, NHTSA’s most recent data shows that in the United States there is an automobile crash every 484,000 miles.

In the 1st quarter, we registered one accident for every 4.19 million miles driven in which drivers had Autopilot engaged. For those driving without Autopilot but with our active safety features, we registered one accident for every 2.05 million miles driven. For those driving without Autopilot and without our active safety features, we registered one accident for every 978 thousand miles driven. By comparison, NHTSA’s most recent data shows that in the United States there is an automobile crash every 484,000 miles.

Vehicle Fire Data

2020

From 2012 – 2020, there has been approximately one Tesla vehicle fire for every 205 million miles traveled. By comparison, data from the National Fire Protection Association (NFPA) and U.S. Department of Transportation shows that in the United States there is a vehicle fire for every 19 million miles traveled.

In order to provide an apt comparison to NFPA data, Tesla’s data set includes instances of vehicle fires caused by structure fires, arson, and other things unrelated to the vehicle, which account for some of the Tesla vehicle fires over this time period.

2019

From 2012 – 2019, there has been approximately one Tesla vehicle fire for every 175 million miles traveled. By comparison, data from the National Fire Protection Association (NFPA) and U.S. Department of Transportation shows that in the United States there is a vehicle fire for every 19 million miles traveled.

In order to provide an apt comparison to NFPA data, Tesla’s data set includes instances of vehicle fires caused by structure fires, arson, and other things unrelated to the vehicle, which account for some of the Tesla vehicle fires over this time period.

2018

From 2012 – 2018, there has been approximately one Tesla vehicle fire for every 170 million miles traveled. By comparison, data from the National Fire Protection Association (NFPA) and U.S. Department of Transportation shows that in the United States there is a vehicle fire for every 19 million miles traveled.

In order to provide an apt comparison to NFPA data, Tesla’s data set includes instances of vehicle fires caused by structure fires, arson, and other things unrelated to the vehicle, which account for about 15% of Tesla vehicle fires over this time period.


Methodology:
We collect the amount of miles traveled by each vehicle with Autopilot active or in manual driving, based on available data we receive from the fleet, and do so without identifying specific vehicles to protect privacy. We also receive a crash alert anytime a crash is reported to us from the fleet, which may include data about whether Autopilot was active at the time of impact. To ensure our statistics are conservative, we count any crash in which Autopilot was deactivated within 5 seconds before impact, and we count all crashes in which the incident alert indicated an airbag or other active restraint deployed. (Our crash statistics are not based on sample data sets or estimates.) In practice, this correlates to nearly any crash at about 12 mph (20 kph) or above, depending on the crash forces generated. On the other hand, police-reported crashes from government databases are notoriously under-reported, by some estimates as much as 50%, in large part because most minor crashes (like “fender benders”) are not investigated. We also do not differentiate based on the type of crash or fault. (For example, more than 35% of all Autopilot crashes occur when the Tesla vehicle is rear-ended by another vehicle.) In this way, we are confident that the statistics we share unquestionably show the benefits of Autopilot.
