I actually don't ride in Davis that much - I commute to W. Sac every day. When I do ride in downtown Davis, the intersections are never clear, so I end up stopping.
On campus, you spend most of your time dodging students walking in a zig-zag pattern, down the middle of the roads, sometimes three and four abreast, often texting a well. They think just because the campus core is closed to vehicular traffic, that you can walk wherever, however, you want.
