Considering that there are quite well known projects, that used Ada, that
still failed (some in quite spectacular fashion) I would have thought would
have constituted sufficient evidence that the proogramming language used
has little to do with the final system safety.

There are constructs in every language that, if used, are probably
potentially lethal in a system. What seems to be evident, though, is that
using an inadequately rigourously applied development process leads to
important facets of the system being missed. Such development processes
should include plenty of reviews, unit, integration and system level
testing and reviews of the results obtained.

I am not sure of the current distribution of languages in automotive
projects at present but I am sure that you will find quite a wide range,
including assemblers are still in there.
