You might have also seen the AUTOSTAR Rust in Automotive Working Group announcement recently[2].

[2]: for some reason the announcement was removed from the "News and events" site, https://webcache.googleusercontent.com/search?q=cache%3Ahttp... but it is still available as a PDF https://www.autosar.org/fileadmin/user_upload/20220308_RustW...
It would be great if AUTOSAR would encompass Rust as well, currently I think they are only evaluating it.
