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.
