great article by Marion Renault

only 5% of ems calls really need lights and sirens

so the real challenge is - can the dispatchers really figure out which
5% of calls are the critical ones?

maybe we need to break this down into 2 problems -

1. going to the scene - is time critical?

2. going to hospital - is time critical?
