i'm not familiar with service=emergency_access
emergency=yes is what we're supposed to be using in association with
access=no or access=private
access=emergency is not so far as i know standard, i used it a lot and
have been meaning to go
back and convert the ones i entered to use emergency=yes

it's appropriate to use it for connectors for motorways that are clearly
signed no u turn.

this case is my interpretation.

you need to be a little careful about "emergency vehicles can drive
anywhere". under NY state
law, for example, emergency vehicles have carte blanch to ignore any
sort of turn or
directional restriction, but fire department officers are often wary of
actually doing this
due to the risks involved. on the other hand, they certainly will use
turn arounds like
the no-u-turn u turns on the motorways. emergency services routing is a
tricky business
that i'm still feeling my way around.

the current situation of overloading of emergency= does present some issues.
