Emphasizing speed over frequency can make sense in contexts where everyone is expected to plan around the timetable, including peak-only commute services and very long trips with low demand. In all other contexts, though, it seems to be a common motorist’s error. Roads are there all the time, so their speed is the most important fact that distinguishes them. But transit is only there if it’s coming soon. If you have a car, you can use a road whenever you want and experience its speed. But transit has to exist when you need it (span), and it needs to be coming soon (frequency). Otherwise, waiting time will wipe out any time savings from a faster service. Unless you’re comfortable planning your life around a particular scheduled trip, speed is worthless without frequency, so a transit map that screams about speed and whispers about frequency may simply be planting confusion.
