I have a weekly commitment that leaves me driving home (~40min) at 9pm, and I usually eat dinner (just a sandwich) while I drive. That also has the advantage of making it so that I'm not eating an hour before bed.
If I know that I need to call someone, I'll usually try to schedule that call while I'm driving. I used to take meetings while driving as well, though I stopped because it was perceived poorly by others.
What's sort of sad is that I can take public transit to all of my regular commitments, and that lets me keep doing something (reading, working, whatever). The schedules are poor, though, and they blow my commute times completely out of the water. For example, I've got a 5-7pm commitment that is a 15-minute drive one way, but if I wanted to go by bus, I'd have to leave at 3:30pm (latest it comes before I need to be there), and get back on it at 8pm (the earliest it comes after I'm done).
The lack of self awareness here is astounding. You’re in control of a two ton bullet, please concentrate on the road. Killing somebody because you’re not paying full attention is not a good look.
