Always sad for the people and next of kin involved in any crash - even more so for fatal ones.
Even so, when either facing public/social or journalistic criticism Tesla sometimes has no choice but simply show the logs.
Re. prev. posts from Discoducky, Tesla has made the hard choice to invest deeply in making (or reverse-engineering) very low-level software for all the hardware controller components and sub-components. Not only can Tesla do over the air upgrades, they can use that capability to query/mine very granular types of data for example. This can be relevant in any crash, where the situation on the ground is, for some reason, not clear.
My guess is that Tesla can pull for example, but not limited to:
Now, I don't know if they can do so in all cases, but I seem to recall when a Tesla crashes, it tries to send (if networks are reachable) a few packets of data to Tesla, re. location of crash, and perhaps other things. Now aware of how much Tesla can pull remote and how much requires physical access to the vehicle. Would make sense if it is case-by-case, depending on how damaged the Tesla in question is.
- Driver-side-weight-sensor (driver present or not)
- Braking, how much force and when
- Airbag: deployed or not
- AP/FSD: Enganged or not, when, warnings raised, warnings headed, etc.
- Impact-sensor: Car impacted when and how much
- Steering wheel: turned how much and when (perhaps rolling 10 sec window)
@Discoducky: Please correct if I am mistaken in my interpretations - iff you are at liberty to say.
It sends a lot more than a few bits of data. It sends all the info regarding the crash it has (GPS coordinates, rate of speed, pressure sensors activated in the car and how much each passenger weighs, if and which foot pedals were pressed and how much, battery status details galore, etc.). It's a virtual treasure-trove of information.
EDIT - and video of all cameras about 20s before the crash through the event. Almost left that part out. This, however, takes longest to send and is the part most at risk of getting cut off if the damage to the car is too extensive or cellular signal is garbage.
