This particular call has raised some concern for me lately... To put it simply - it occurs/generates far too often to be considered even close to being realistic.
I'm not entirely sure if it is possible off the top of my head, but it seriously needs to be reduced.
The call seems to generate around 6 - 8 times a day, which is ridiculous. Having that many crashes in a YEAR would be highly unlikely for most areas. Can this please be looked into in the very near future? It requires a considerable amount of resources too, which is another factor... Particularly when I've had 3 happen at the same time
