Skimming MISRA C, it seems to be a collection of either extremely limiting or ineffectual directives. An example of each:

> Dir 4.12 Dynamic memory allocation shall not be used

> Rule 2.2 There shall be no dead code

This provides nothing approaching the guarantees of safe Rust, as far as I can tell.
