You're probably right in this assumption. But it can be different for
other POI's, like stops or toll booths. I can remember now several roads
that end in a stop after some hundreds of metres or even kilometres of
straight line. And the same can be applied to a motorway in which you
have to stop at a toll booth. What's your opinion?
