It could happen to anyone of us on this thread, including those calling for a charge
I think on the original thread where people seemed out for blood, someone mentioned that this happened to a relative of theirs, had a first fit at the wheel and the accelerator was stuck under the rigid foot of the driver.
I think it was clear that if this had been obviously dangerous driving or neglectful driving/drunk driving a charge would have been made very quickly. i felt it was obvious from the delay that this was a complicated medical thing but got shouted down on other threads
Poor families and poor driver. Awful all round.
