That's not any more useful, though, is it, since you don't know the distance between exits 7 and 8?

If you're running low on fuel, and you know you need exit 32, and you come up on exit 15, you don't know if there are any exists between 15 and 32 but you can at least judge whether your car can make it 17 more miles on its fuel.

If you're low on fuel, and you know you need exit 8, and you come up on exit 7, you know it's the last exit before you need to get off the Interstate, but you don't know the distance between exits 7 and 8, so you can't make an informed decision on whether the fuel you have remaining is sufficient to get to your exit.

To be fair, your point is the argument my SO has been battling me with for the past decade :-)

You know you can refuel before the light comes on, right?
