And that is terrible.
But lets get a bit of perspective on it:
http://www.road-safety.org.uk/driving/advice-for-drivers/road-safety-statistics/
On Scotland’s roads in 2013 there were:
A total of 8,986 reported injury accidents in which 11,498 people were reported as being casualties;
1,844 people reported killed or seriously injured (172 of whom died);
6,961 casualties in cars, 89 of whom died;
1,747 pedestrian casualties, of whom 38 were killed;
773 motorcyclist casualties (of whom 23 were killed);
883 pedal cyclist casualties (of whom 13 were killed);
1,062 child casualties, 143 of whom were seriously injured (9 of them died);
464 child pedestrian casualties – 92 were seriously injured (5 died).
So yes, the occasional fatality does happen. But the scale is miniscule in the overall bigger picture.
