Safety drivers at proper AV companies usually go through several weeks of rigorous classroom instruction and test track driving with a professional driving instructor, including lots of practice with the real AVs on closed courses with simulated system faults, takeover situations, etc. Anecdotally I've seen trained safety drivers take over from unexpected system failures at speeds near the floor of human reaction time. They are some of the best and most attentive drivers on the road. Average folks beta testing Tesla's software for them are woefully under-prepared to safely mitigate the risks these vehicles pose. In several cases they've meaninglessly died so that Tesla could learn a lesson everyone else saw coming months in advance.
