Also, it's also a reminder about what your local emergency services have to look at and deal with on a daily basis. They do such an amazing job (perhaps too good) of hiding the reality of serious and fatal collisions from members of the public, that they don't get the appreciation they deserve.
Just remember, when you see on the news the 30 second snippet that there was a fatal collision, it could have involved someone burning to death in a car, someone hideously maimed, someone who was alive talking to the emergency services for some time before dying, or someone who was calling out for their mother before they died - it's ridiculously traumatic and it's only when you see "normal" member's of the public reaction to this sort of stuff, you realise what fortitude the emergency services have to have to not only not let it affect them, but then to do a job, search a body, and tell the relatives.
Often at these collisions, there are "normal" members of the public who are fainting, in hysterics physically and uncontrollably shaking - but your friendly emergency services have to just get on with it.
