When I rode regularly in college anything less than about 20mph was considered "pedestrian" and there were days in group rides that we averaged over 25mph. There were some rides averaging very nearly 30mph.
If you've got that kind of a background 12.5mph doesn't feel right. So maybe not entirely pedantic.
I just did a distance ride (100 miles per day) on my mountain bike loaded with camping gear on dirt paths. Average pace was 10mph, there are more than just carbon bikes on flat roads...
