Players usually have their characters travel on foot at lower levels, maybe on horseback if they can. As most low-level PC's aren't rolling in coin, this makes total sense.
However, once they start getting some serious coin, I feel like more PC's should upgrade their travel arrangements to a wagon. Wagons are more comfortable, they provide shelter, make it easier to transport luggage, can give cover in a fight, and shows that you're not just some itinerant murderhobo.
Abadar's faithful often use the Safecamp Wagon which provides some lovely features and can shrink down to the size of a child's toy. I could see a party making similar upgrades to their wagon, like the Alarm spell, increased hardness/HP, make it larger on the inside, etc.
My next game with a lot of time on the road will feature some cool wagons that PC's can get.
