Your point is well taken but Misra-C significantly reduces many of the C
language issues.

A second point is may automotive applications are written using
implementation rules that are a subset of Misra-C.

There are implementation process standards for most industries that
require reliable application implementation.

This is true for automotive, medical devices, and aviation. It is
possible to make applications reliable independent of the implementation
languages.

One of the simplest ways of making applications reliable is having an
application beta tested for a significant amount of time on a real
application following the last change before release.

Automotive engine controllers require two years data after the internal
release until the code is shipped.
