A non functional tank. It is the same as a painting of a tank or a statue.

A broken car is still a car! If I pushed a broken down Honda Civic into the park with the gear shift set to neutral and left it there, surely that would break the rule?

Is a sculpture of a car a vehicle? The broken car is still a car because the intent of the thing is stop to be a car. A memorial tank is not intended to be a vehicle, but rather be a sculpture. A sculpture is usually not a vehicle, even if it may look like one.

In the absence of a definition of vehicle I chose to define it as any device that is a conveyance. Thus a wagon, rowboat, and skateboard are all vehicles in the park (even if not in use).

However, the tank was not functional. Since it cannot convey it is therefore not a conveyance and therefore not a vehicle. It’s only shaped like a familiar one.

I matched the majority only 11% of the time.

I can't find any definition of tank that doesn't describe it as an armored fighting vehicle. If it's a tank, it's a vehicle. If it's not a vehicle, don't call it a tank.

The scenario said tank. A tank is a vehicle. No vehicles in the park.

Edit: I matched 11% as well!

Does the tank ever become not a vehicle? Rusted to the frame?

In my view no matter what the tank originally was, it ceases to be a vehicle when it can no longer act as a conveyance. A tank (and any vehicle) is not just a form, but a function. Is a car with no motor, no tires, no transmission a vehicle? I do not believe so, because it cannot and lacks the possibility of moving without a substantial transformation.

Is a bicycle only a vehicle if equipped with a human?

The bicycle is quite capable of acting as conveyance for a human (or perhaps bicycle peddling robot, or trained animal) in its current form, so that's an easy "no" from me.

As I said, if the thing can (i.e., without significant, non-trivial alterations to its current form) act as conveyance then it is a vehicle. It need not be in the act of conveyance, nor must it have an independent means of propulsion.

Edit: my simple rule breaks down when thinking about a flat piece of wood attached to rope. My mind says that's only a vehicle if someone chooses to use it as such for pulling objects or people. I'll leave the search for a universal maxim to others, it seems.

Interestingly, in Brazil's transit code a person carrying their bycicle unmounted is considered a pedestrian. Otherwise, they're a non motorized light vehicle.

Belgian traffic code says "Het niet bereden rijwiel wordt niet als voertuig beschouwd.", i.e. "The bicycle that is not ridden is not regarded as a vehicle." When you walk next to your bicycle, you're effectively a pedestrian here. No idea how things are defined in other countries.

Pretty sure that bit’s broken. Anyone seen it give any other value than 11%?

A memorial tank is not a vehicle, it’s a metal sculpture. The intended use is no longer to move, but rather to sit there.

I applied the same mental model and also ended with 11%. It's a vehicle if it is transporting people, things, or itself (e.g., the R/C car).

> 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.

The 11% seemed odd to me... I selected only 3 violators: the car, the ambulance, and the police car, and those seem to be the only majority-chosen violators according to the graph so I would think I matched 100%?

I was similar, a bicycle is a vehicle and I even called the toycar a vehicle because I think they were talking about those cars kids build and race down hills. I was considering more about "how is this typically powered?" and "what is the F=ma if it hit someone?"

If it's typically not human powered, a human typically rides it, it's typically heavy, and typically accelerates enough to seriously injure another person with minimal damage to yourself it's a vehicle. That's why skateboards and horses aren't vehicles but the bike and toy car was. Even the bike is dicey but it's fairly unanimous throughout the world that a bike is a vehicle.
