GOOG's self-driving car written in FIOC

Problem?

C/C++ (like every programming language) does not require variables to be correct, as

int fib(int n) {
        int p = 1;
        while (n--)
                p * n;
        return n;
}

This means that C/C++ can't even detect a trivial typo - it will produce a program, which will continue working for hours until it reaches the typo - THEN go boom and
you lost all unsaved data.
