The version of code tested doesn't necessarily reflect the current state. Bugs are introduced and things that worked before, stop working properly after an update. One such example of this is at https://www.reddit.com/r/teslamotors/comments/8a0jfh/autopilot_barrier_lust_201812/ https://www.reddit.com/r/teslamotors/comments/8a0jfh/autopil... > Yep, works for 6 months with zero issues. Then one Friday night you get an update. Everything works that weekend, and on your way to work on Monday. Then, 18 minutes into your commute home, it drives straight at a barrier at 60 MPH. > It's important to remember that it's not like you got the update 5 minutes before this happened. Even worse, you may not know you got an update if you are in a multi-driver household and the other driver installed the update.
