I love Volvo cars. I hope they have enough investment in support and engineering, because Rust isn't an easy language to pick up. I wouldn't want to escalate minor software problems through the management that needs engineering team's response and I'm waiting because there is not enough people to support across continents.
I welcome new Rust jobs, I myself have attempted to learn (and fail). But having it in a customer facing and a software embedded in customer's car is not what I expected.
Maybe starting in a backend service that they can monitor and deploy changes in events of outage would be an easy start. For something a scale of customer owned cars, I hope they are prepared.
If you pick a new tech that is interesting to potential employees, it can really help hiring. You can get a lot of experienced applicants wanting to sink their teeth into the new tech. Lots of places found this when they went with Go. Unless you need to produce vast amounts of mediocre code, you generally want to hire the people interested and able to pick up a language even though it isn't easy.
