For local distance use blocks instead of feet/miles
Please give directions like humans, not a robot. If an upcoming turn is 2 blocks ahead, that is what a human would say . . . not 500 feet ahead.
When on a highway, telling me that an exit is 1/2 mile ahead is fine.
However, when on local streets (even 4 lane local roads) pease at least offer me the option of telling me how many blocks ahead the turn is.
