Roadsigns might act as a way to go quickly to the places they direct you to.
For example "travel ferry" at the south cross Arelium road sign would take you
to the ferry after a few seconds and cost a few eps. This would save a little
game bandwidth and make life a lot easier for everyone.

And then those roadsigns could be made so that players could turn them to
point to other directions! And when you're traveling to 'ferry' you might end
up into a deep forest in the middle of nowhere.

Another alternative could be a built-in trig to BatClient.

The trigger would recongize the sign and based on it offer a list
of destinations for the user to run to.

After an initial set of paths based on roadsigns, users could make
their own paths to scenics quite easily.
