Can we request that members refrain from speculation as to the cause of the incident please. There is nothing to suggest that this is an act of suicide, and it is best to wait until the official verdict is given in due course.
As many of the regulars to the forum will be aware, suicide is a sensitive subject to many people, so please post with due consideration.
As has already been mentioned by others, our thoughts are always with all of those affected by such incidents, be it the deceased and family, the driver and family, and all those that have to clear up in the aftermath.
