Yes, it does. It does not force you along one path or another, and if one is without danger and the straightest path is harmful, I doubt that you would have the spell fail. Or if you have a ground speed faster than a fly speed, it will not force you to run if the floor is lava, you will use your fly speed. And it will not force you to use powers or spells to go faster even though they might be available, etc.
The fastest available without harm, otherwise the spell just fails.
BTW, I have looked for the JC tweet and could not find it from a quick search, I think it would be interesting to look at it in detail.
