26262 covers system failures that produce unsafety, like broken accelerator sensors. ISO 21448 (SOTIF) covers system failure to detect and respond to the environment appropriately (e.g. does the radar detect small children?), which is also a common concern for people in my experience.

Both are acceptable standards, but ISO 26262 is a behemoth of a standard that most people have never read. Many companies don't even make the full standard available to their development teams, let alone educate people to employ it effectively. Similarly, MISRA is fine in theory, but the practical usage often ends with running code through an automatic checker that can only detect half the rules.
