I'm trying to get my insurance discounted on my car. I should slap a "written in Rust" sticker on it. Safe driver discount?
It makes sense. If your car is covered with rust, you should be almost sure that no one will even try to steal it. :)
Given that automotive control software is apparently a huge mess right now, and a rapidly growing attack surface, a more disciplined rewrite in Rust might actually be enough for an insurance company to consider...
