I ride the same route home every day, mainly because it's the safest route I've found. Complacency happens, though. After zipping through a parking lot and avoiding the three cars that came out of nowhere, and feeling cocky, I zipped around a telephone pole and back onto the sidewalk (normally ride on the street, but not on this section of the road) where I promptly lost traction on my rear wheel and went down onto my chest. Two weeks of soreness has made me plenty more attentive.
