[HT] Cost of a Stagecoach Ticket

[Jinumon]

Something I've been running into a lot, whether it's in other GURPS books or historical references, is a discrepancy between how fast it says it says a stagecoach travels in GURPS High-Tech ("an average of 8 miles an hour") and other sources, which estimate between 4 and 5 mph. Is the sidebar in GURPS High-Tech assuming a paved road? I guess because it's under the heading "On the Coach Across America" I assumed that was an average for a trip, you know, across America, plains and backroads and all. Is the sidebar just inaccurate?
