Time, that is, to think about the job, the future, changes that ought to be made. People living hurried lives need thinking time. Slow traffic often provides it. I know working couples who ride to work and back home together, and that's a private and good time for them, when they can talk, and there's no chance they can be overheard. Women put on make-up, pluck their eyebrows.
Men comb their hair, squeeze their blackheads, retie their neckties.
This is one of my hobbies, and I get valuable ideas from it. SE's sing while waiting at lights. They rehearse speeches they intend to make when they get to work, or back home. They wave a hand to emphasize a point. They pause and smile when the audience applauds.
