When i say multitask I mean that more literally. If you’re driving you can’t read, if you’re a passenger on public transit audio won’t make you motion sick, if you are cooking or cleaning you can have it on in the background, etc.

Reading requires the full use of your eyes, no way around that.

Fair enough - we have different definitions. If I have audio on while driving or cooking or cleaning, I can only half listen, I miss a lot. I have to be very careful with what I listen to while driving, lest it take my attention away from the road, so I only half agree with you.
