I sketched while driving. O-o-o- Dangerous! Worse than texting? I had a commute to South Austin to a 6:30 PM class. That's over, now. Nevertheless, I discovered a calming practice when the alleged traffic was more like "parking". Little doodles or sketches. It works to pass the time when waiting - in line, your turn, at the bank, etc.
