OOP is not Singleton, it is "class Car extends Vehicle {Tyre tyres[4]}" etc

I responded to that. It’s nonsense which doesn’t work:

What behavior are you going to out in vehicle? Here are a few potential subclasses you’ll need to consider:

- hang glider

- wheelies

- train

- skis

- lawn mower

- windsurfing board
