Sitting in traffic trying to stay productive.

What do other entrepreneurs do while driving and stuck in traffic. Me personally I make all my phone calls. I will respond to texts when I get them (not driving), and tell them I will call them back during the time I know I will be on the road and can speak safely, handsfree. I feel like this is a good use of my time sitting, otherwise unproductive.

I wonder what other people do? Listen to podcasts? Plan? Strategize? Recite their sales pitches to themselves? Catch up with your team? Random check in calls with clients?
