Sometimes it’s shifting gears. Clutch leg can get annoyed in heavy traffic. So, foot off the clutch, out of gear at a light for a little sigh of relief. Probably takes an extra second or 3 to get going. No phone involved.
You can switch gears when you see yellow light already so you don’t lose green light time. It takes me something between 0.5 to 1 sec to switch to first gear when my foot is at rest (not counting reaction time).

In 2024 that’s increasingly rare and I can usually see them using their phone plain as day from behind.
