These can be dangerous, if used by a navigator to show/warn the driver 
when you have to yield or have the right-of-way for the junction ahead 
(think of outdated map data).

But the information could be used behind the scenes for routing 
purposes, i.e. for junctions without traffic lights where you have to 
yield, add a little more to the cost than for junctions where you have 
priority. Especially left turns (in right hand side driving countries) 
behind a yield sign can be time-consuming.
