That may be the case in some countries, but in the UK there are
limitations on what laws emergency vehicles can and cannot break. 

Countries also have differing definitions of what constitutes an
"emergency vehicle" for these purposes. A regular doctor on his way to
an emergency, organs for transplant for example... in the UK they cannot
use blue lights, and "people die" because these vehicles get stuck in

See this website for all the complexities: 

The question is, how to model this in OSM? Or do we just model for
normal cars? Just like for trucks, routing for emergency vehicles needs
parameterisation for the vehicle characteristics and the specific use to
which it is being put *at that moment*.
