My mind is stuck in Medeival but it could literally be something incredibly different

I'm thinking locomotive.

Maybe railroad but they’re also seen nowadays.

I guess it could just be a statue or something, if travel means people travel to see it.

Something related to travel that isn't a vehicle that you don't sit on/in usually that also can't fit in a garage.

would it be a horse and buggy or a carriage?

No!

Maybe we ask if it transports people. That could help with the travel thing. But I’m too afraid to ask that.

BARELY can’t fit in a garage / maaaaaaybe it could

Idk how many questions we have left but I think figuring out the time period may be most useful.

I think we have 2 questions/guesses left.
About the catapult --- that is more a weapon than transportation.

wait. what about something like a chariot? You stand on those, right? Can you sit in them too?
Would that fit with with all the other answers.

Related to travel but not a vehicle feels like the key

that should fit in a garage though...what about something specific like the Trojan Horse thing?

14. Metal was used in its construction

This reads like it is something one-of-a-kind or super well-known which brings me back to the tourist attraction.
