Did you click on that Cornell link?

> The term “used for commercial purposes” means the carriage of persons or property for any fare, fee, rate, charge or other consideration, or directly or indirectly in connection with any business, or other undertaking intended for profit.

Wait, "carriage"? Click on the source link and go up a level, and you'll see it's talking about transporting people and things in vehicles: https://www.law.cornell.edu/uscode/text/18/31. It's part of "18 U.S. Code Chapter 2 - AIRCRAFT AND MOTOR VEHICLES": https://www.law.cornell.edu/uscode/text/18/part-I/chapter-2.
