There were many eye-witnesses at the scene- parents and teachers at the school. The driver was conscious at the point of impact, got out of the car unaided immediately after, and was not drowsy, hadn't wet herself etc. It is implausible that she left the golf club car park 30 metres up the road, suddenly had a fit which had resolved and had not after effects, all within the space of 1-2 minutes.
All the people stating that 'scans must have been falsified' or 'doctors lied' etc clearly do not have a clue about epilepsy and how it is diagnosed.
Epilepsy is not diagnosed by a scan. There is nothing to see on a brain scan, unless there is a brain tumour or similar pathology which has triggered the seizure. Her scans were clear (same for many with epilepsy)
An EEG shortly after a seizure would often pick up changes in brainwaves. It is possible that this wasn't done within the timescale, or that no changes were detected. After a couple of hours, the window for detecting this will have passed.
There is no medical evidence to back up her version of events. The driver has been diagnosed on her self-reported history. This is the same for many who have a diagnosis of epilepsy. So no doctors lying or scans falsified.
With the drivers lawyers pushing the narrative that this was a tragic accident, the CPS would need to prove that she didn't have a seizure, or was unfit to drive for some other reason. Once they have ruled out drugs/ alcohol/ previous medical condition it all hangs on her word that she had a seizure and it is actually impossible to prove that she did not. The expensive lawyers are the main factor here because they will continually cast doubt 'but could she have had a seizure....? ' and of course the answer from any doctor will always be yes,it is a possibility.
The anger from the girls parents and others at the school is understandable. Everyone knows the seizure story is a load of rubbish and justice has not been done. More will come out at the inquest.
