I was reminded of yet another reason I'd rather bike the 10 miles to work than drive, that we don't often think about: traffic accidents. I turn onto a divided 4-lane near the end of my commute. Looking back after my turn (why is there no traffic?) I saw the emergency vehicles working an accident at the prior intersection. Thinking about getting stuck in that backup, or worse, involved in the collision, it sure felt nice to glide into work without interacting with any of that.
