Weird accident.
Good thing about the Tesla, is that VicPol will get forensic access to the vehicles computers, cameras and data.
They'll know if it was on autopilot - and if it was, there will be camera footage of what the driver was doing (i.e. texting most likely - allegedly).
They'll know everything, in a short period of time, every input and output, speed, GPS -everything. Even with dashcams in standard cars today, the level of data would not be the same.
Hopefully, with that evidence - clear paths to justice can be formed quickly.
That being said, there is someone with very severe sounding injuries...I hope she pulls through
