How about "log error and enter a safe state"?

"engineers" the best you can do is to make it easier to do things right.

unchecked exceptions that aren't declared and checked by the compiler.
to just stop because an assertion stopped he engine controller?
be performed with the same software as will be deploeyed.
As an example of an assertion which can be removed.
We have an FPGA which contains registers.
In my code I want to access the FPGA registers as a struct.
assertions will not cause a problem in a production system.
If I however write the following code.
Then I have totally misunderstood what assertions are all about.
Here is another assertion that can be removed.
The latter example triggers an error, so the code needs changing.
The code is not needed in production.

Because sometimes it is. We've supplied examples.
The choices are not limited to "leave all assert()s in production code"

In the event of failure, the C assert() macro calls abort().

Nobody is advocating for removing all error checking in production code.
the right response, but that's far from universal.

make the system crash in some uncontrolled way.
Because assertions add code size and reduces performance.
The bug is that you did an assertion, instead of validating data.
design is flawed. You used assertions, instead of run-time checks.
Learn the difference between assertions and run time checks.
You need to realize your assertions can have bugs just like your code.
