I don't doubt it. In Morrowind, many fans were disappointed that they couldn't ride silt striders in real time, and one of the most popular Morrowind mods was one that allowed the player to do so. Personally, I think it would be pretty awesome.
Which is why they amount to ingame fast travel points. I'd hope carriages were in real time with the option to skip the journey.
All in all it's just catering more-so to roleplayers.
