iOS Intermediate Swift 2 Object Initialization Initializing Superclasses

I am still confused on the purpose of convenience class

I understand the purpose of initializing classes, but I am still lost on the purpose of convenience initializer.

In the video two classes are created: Vehicle and Car. The Vehicle class calls a convenience init to assign the name "Unnamed", and the same for the number of doors for the Car initializer.

What I am confused on is how this is different from assigning the value directly in the class, or even in the designated init. It seems like a lot of extra code to do essentially the same thing. Am I missing another concept here?
