> It's a vehicle if it is transporting people, things, or itself (e.g., the R/C car).

If transporting oneself counts, are all the people in the park vehicles? And all other animals, down to the microorganisms, that are capable of self-transport?

Or I suppose even in the case of transporting other things, people would count as vehicles if they are carrying anything or wearing clothes?

I realize this is the point this article was making, but I must say this is exactly the level of pedantic-as-the-point conversation that I no long put up with in my adult life.
