oh dear,You cant pass judgement Pomp, you dont know if they were speeding or not, also you dont have to be breaking the limit to be driving dangerously. it could have been a number of things:
- Missed the slipway and tried to exit the motorway to late
- fallin asleep at the wheel
- some sort of medical condition, ie heart attack
- drink driving
- drugged and driving
- another car may have clipped it and left the scene not knowing what had happened
We cant really comment until we know the facts.Even if it was the drivers fault, My compassions go out to his\her family and freinds.
