To the extent that the analogy works, it doesn't help your case: nobody these days builds or learns how to build a car from scratch, without access to an existing car. It's not only that you're typically making a modified version of an existing model: you also use a car to get to the factory, you use existing vehicles to transport raw materials and tools to the factory, etc.
In any case, as others have pointed out, it's not like you need to use a full {Lisp, Haskell, ML} compiler to implement (say) tail recursion. It's that you bootstrap: as soon as you have a minimal viable {Lisp, Haskell, ML} compiler, it makes sense to use that instead of C to implement other features.
