I haven't used Waze, but this is something that I do consciously. I find it's more beneficial for my mental well-being to choose a less direct, longer route, that I can drive continuously on, over a quicker but more congested route with lots of waits in queues and at traffic lights.
I'm reminded of a comment I read on HN the other day, which expressed that anger arises from being blocked from progressing by things outside of your control but not outside of possibility. People generally don't care if something takes a long time, they care when they notice reasons why it need not take as long a time as it does.
I also experience this. When I'm actually driving I feel like I'm actually doing something. My blood pressure rises if I'm queued up at a light for 3 cycles. In theory, I want more roundabouts in my area but I don't know if it actually increases flow.
