Speed must be part of it. Low sun and going into the back of a parked car or other obstacle is a common mistake, and road bikes get up some good speed on most rides. Many riders pass 80kmh on a regular basis, which doesn’t leave a lot of room for error. I’m rather slower than that, but 50-60kmh would be a daily event.
