A High Speed Tesla Crash Captured on DashCam with Telemetrics

Post by MSI »

Saw a Linkedin Post by Noel Lowdon
Which included:
  • This video (note i downloaded and edited the video, added other videos, etc) is taken from ‘Green’ @Greentheonly on twitter on Twitter who is well known for their research with #Tesla vehicles and various vulnerabilities.
    Please visit his account (link below) for the full thread on this but food for thought for forensic collision investigation.
    The video shows footage recovered from the vehicles embedded systems with EDR and canbus data overlaid in the bottom left.
    Green concluded...
    • The people that bet on driver asleep were probably correct. The driver did NOT hold the steering wheel and the autopilot did a "strikeout", BUT when that happens the car does not stop steering (unsafe) and continues in lane.
      What made matters even worse - the driver had their foot on the accelerator pedal gradually increasing the pressure and increasing speed. While normally AP does not operate above 90mph, but it will keep steering you don't take control.
      The biggest gap in this whole thing is - the car clearly sees an obstacle, sure it sits in the same lane, but why not override driver accelerator input pedal misapplication-prevention-style and just match speed? Sounds like a safer decision? Hopefully this could be fixed?
    Interesting stuff !

Here is the time history of the AutoPilot steer which included this comment:
(and note the scale on the left, approx -3 to + 6 degrees steer is for steering wheel angle and the actual steer change is at front wheels 1/20 or so of that (so approx -.15 to 0.30 degrees) need to look up the actual steering wheel ratio)
