My Garmin and now my TomTom navigation system in my car often shows no
default speed limit in city. They must rely on information posted on way
vectors. Driving in an unfamiliar area, you don't often know the default
speed limit. It would be great if we posted maxspeed on all city streets,
but it just isn't happening. I'll get around to doing my city, but doing
much more would be very time consuming.

Certainly we'd need consumers to use the data. But if we did post the
maxspeed in the boundary/relation, I would suspect that it would start to
used.

I do believe, but don't know for sure, that consumers are already aware of
which boundary they are in. For example, most searches default to the city
you are in.
