Certainly has a huge impact on my own mental health. My commute options are bike (2hr total pretty much without fail) or drive (on average 1:15 total) and even though the 45 min cost is not nothing, I know I’m happier, more pleasant and have less migraines when I commute more steadily by bike than drive. Doesn’t even matter about weather. I really appreciate my time on the bike to get some exercise, be outside, and just generally not be in a car.
