Learned about this last month from HN [0].

Subsequently took a 10 hour car trip where my wife and daughter both reported this feature allowed them both to read their books and articles while I was driving, which was definitely not the case on any prior road trip. So, add +2 to whatever Ns you're tracking.

Told my spouse about this feature when I learned about this a while back too. They have terrible motion sickness to the point that just shooting a quick text was a gamble.

Since they put this setting on, they can happily use their phone with no motion sickness. So +1 to that N.
