Is it garbage logic?

Dev: "The compiler's automatic error checking didn't catch the array overrun in my code, resulting in a costly security breach!"

Compiler Vendor: "Our data shows that compiler diagnostics, when used by a skilled and conscientious programmer who is prepared to review and test his or her code, reduce software defects compared to no diagnostics, making software development safer."

Your examples are garbage logic because array overruns are so harmful that they should be hard errors. Of course, this requires a runtime cost, that can be elided in most cases by the compiler's optimizer. But even low level languages nowadays can be safe by default (see Rust) - the unsafe behavior should always be a conscious, well studied decision by the developer.

You’re comparing getting decapitated by a truck to an array overrun, which might be a sign your analogy is strained.
