I gave this feature a try and it didn't work for me. I was curious to see if it was effective, so I asked my wife to drive and I tried to read in the iOS "Books" app with the dots on. I think within 5 or 10 minutes I was feeling pretty sick, and stayed that way for the rest of the drive. Hopefully others have better results. I'll have to stick with audiobooks when in motion.

That’s unfortunate. I didn’t know this feature existed so I’ve yet to try it out. Fingers crossed
