I changed jobs in August but was lucky enough to continue to commute to and from work relatively easily, actually adding some mileage to the commute. My ride to work varies little day to day, but returning from work I have roughly 8 to 10 basic different routes that I can choose from. Almost all of them involve a combination of bike path and street travel, so I don't see much of the "safety" feature in sticking to a consistent route either.
