I'm not sure I follow your question. Are you saying that by biking you don't care as much or that you find your arrival times to be more consistent?

Our office opens at 8:00. Some people get here earlier, some people later. Most folks are in by 8:30 and I try to arrive by then. No one would say anything directly if I started showing up at 9:00 but there would be comments. I know because people grumble about other people consistently taking too much liberty with their start time.

None of it matters too much if you're doing your job but I have staff that really do need to be in the office by 8:30. If I start showing up later it sets a bad example. I also like to leave at a decent hour so I can be with my family. From that standpoint getting to work late and leaving late is undesirable.

Anyway I actually got into work a little early today. And I do find that by biking I'm less susceptible to being delayed by traffic problems.
