There are a lot of unanswered questions but it seems to me there is demonisation and a witch hunt against this 'driver' with some people determined to have her held to blame for the death for various agenda reasons.
My agenda's really simple. If you're the person sitting on the left (US/LHD), you are responsible for that vehicle. AFAIK, that's still the current legal position as well. A person died because the driver wasn't paying attention.
