A very common mistake is to commute what you’d drive.
This right here.
When I was living in western NY and bike commuting, I took the Towpath along the Erie Canal instead of following the roads to work. It ended up being about the same distance, but was significantly less stressful to not worry about getting clobbered by a driver not paying attention.
Someone posted a screenshot from 4chan where they were talking about how to fake submissions… 😠
