Once you have roads and speed limits, the question of "which roads are the quickest way to go usually" can be determined by an algorithm. I guess to some extent it's a question of whether or not a street map database without speed limits is "good enough". I'd say it is not. At least not in the more heavily populated areas of the world. I suppose all the bicyclists in OSM would disagree with that, but they don't have much use for primary/secondary/tertiary designations either, do they?

Yes, it's an endless debate, so I'll try not to spend too much time on it. I think it is useful to point out the problems every once in a while, though.
