How is it even possible to look at the minimap during laning phase

I just played a game listening to https://youtu.be/j7GXTxzs-ts, which reminds me to look at the minimap every couple seconds. However, I found myself unable to find time to look. I try to keep my movements precise and sudden, but when I move my eyes to the minimap I would move clunkily and slowly and get hit by skillshots. However, backing off every few seconds to look at the minimap doesn't make sense. When I did look at the minimap, it took me like 2-3 seconds to notice where my own jungler is, if any of them are mia, etc.

When is it safe to look at the minimap during lane? Obviously between waves, but sometimes the waves aren't fully cleared, and waiting 30 seconds is soo long.

Or is the issue me not being able to read the minimap in just 1 second?
