Any annoucement including a blog post, company/employee social media post, press release, or news article is fine. Time ends at 23:59:59 on October 31, 2023, Pacific Time. Note that this market depends on a public announcement, so it still resolves to NO if the miles are announced after closing time even if those miles were achieved before closing time.

(Note that driverless miles are NOT the same as self-driving miles. The later includes safety driver miles)
