Tesla just lately launched a brand new replace to its Automobile Security Report, revealing information for all 4 quarters of 2023.
The voluntarily printed quarterly experiences embrace the variety of miles pushed per accident registered when utilizing Autopilot know-how, not utilizing Autopilot know-how, and the U.S. common (the latest information accessible from NHTSA and FHWA for calendar yr 2022).
The info offers us glimpses of how Autopilot improves automobile security, however it has some limitations (extra on that on the backside of this submit) because of the methodology. For instance, Tesla counts all accidents, whatever the trigger, although greater than 35 p.c of all Autopilot crashes happen when the Tesla automobile is rear-ended by one other automobile, the corporate says.

Tesla EV security
Tesla aspires to be one of many world’s most secure automotive manufacturers. Its Autopilot driver help system is promised to supply a big enchancment of security, in comparison with standard driving.
In response to Tesla, the variety of miles pushed per accident registered in 2023, when utilizing Autopilot know-how, different from 5.18 to six.18 million miles pushed.
The outcomes are combined—21% worse than a yr in the past in Q1, 21% higher in Q2, 6% worse in Q3 and 11% higher in This autumn. In different phrases, we won’t actually say that there’s a clear, constant, and noticeable enchancment.
With out utilizing Autopilot know-how, Tesla automobiles statistically observe extra accidents—from 1.00 to 1.52 million miles pushed per accident registered.
Not solely that, the outcomes had been worse than in 2022 in every of the 4 quarters of 2023 (Q1 down 9%, Q2 down 5%, Q3 down 11%, and This autumn down 29% year-over-year).

There’s a important distinction between the 2 modes of driving (with or with out Autopilot) and the distinction continues to extend. Nevertheless, we should observe that the 2 information units shouldn’t be in contrast in opposition to one another, except for offering us with some concept of the numbers.
It is vital to notice that the outcomes are comparable solely inside a specific class (Autopilot or with out Autopilot), not between the classes because the enter information could be broadly completely different (like easy freeway driving or advanced metropolis driving). In different phrases, we are able to solely see whether or not the lively security programs are enhancing over time (and it is also solely a tough comparability), however we won’t examine Autopilot to non-Autopilot driving.
We assume that the correct use of Autopilot improves security, however Tesla’s report doesn’t permit us to judge the distinction.
Under we connected a full chart with all numbers offered by the producer plus NHTSA and FHWA information concerning the common distance between an car crash in the USA.
The distinction is fairly enormous, however as soon as once more, we should not examine the numbers straight. The U.S. common features a a lot older automobile fleet (with fewer security programs), which alone is a giant issue. The U.S. common is 0.670 million miles (as of 2022 since there isn’t a information for 2023 but).

Tesla has its personal model of the chart:

Vital elements:
information for every setting could be collected at completely different driving situations (like easy freeway driving or advanced metropolis driving), which makes the outcomes incomparable between the classes outcomes could be affected by numerous elements, together with seasonality (decreased daylight, climate situations), much less driving throughout lockdown NHTSA and FHWA common for the U.S. (up to date hardly ever) contains all automobiles, additionally previous Tesla’s information concerning the methodology of registering accidents:”We gather the quantity of miles traveled by every automobile with Autopilot lively or in guide driving, based mostly on accessible information we obtain from the fleet, and achieve this with out figuring out particular automobiles to guard privateness. We additionally obtain a crash alert anytime a crash is reported to us from the fleet, which can embrace information about whether or not Autopilot was lively on the time of influence. To make sure our statistics are conservative, we depend any crash through which Autopilot was deactivated inside 5 seconds earlier than influence, and we depend all crashes through which the incident alert indicated an airbag or different lively restraint deployed. (Our crash statistics should not based mostly on pattern information units or estimates.) In observe, this correlates to almost any crash at about 12 mph (20 kph) or above, relying on the crash forces generated. We don’t differentiate based mostly on the kind of crash or fault (For instance, greater than 35% of all Autopilot crashes happen when the Tesla automobile is rear-ended by one other automobile). On this method, we’re assured that the statistics we share unquestionably present the advantages of Autopilot.” assuming the methodology was not modified, we are able to see how every class improves over time
