Asking Siri for "directions to closest" anything doesn't work

There have been times when I've had to ask Siri for directions to the closest store of some kind, like the closest gas station. Often the directions end up going to somewhere completely unrelated, and even when Siri does respond close to right it's to give me a list of nearby businesses, expecting me to read the list and pick something. But if I'm driving, especially if I'm on a motorcycle, the last thing I want to do is take my eyes off the road to read a list.

How do I get Siri to just start the directions to the closest matching business without this needless interruption?
