I've certainly felt like this at times. The smug pedestrian (or bike rider) cruising past a traffic jam.
Thursdays in my neighbourhood are particularly bad for drivers. Our city has late night shopping on Thursdays, so commuter traffic and shopping traffic add together.
In a logical world some of the regular drivers would work this out and take public transport on a Thursday - or ride or walk if it's a short distance. But people tend to stick to habits even if it means sitting in traffic for much longer than other forms of transport would take.
Of course the poor woman in the cartoon is also doing for for her physical and mental health.
