I live about 4 miles from my workplace, and it would be a 10-minute or so drive if I were going directly there. But, I have to drop off/pick up my kids from two different places (preschool and school), so it's more like 45 minutes, counting walking the kiddos in, etc. But the upside is that my DH and I work at the same place (different departments of a university), so we usually drive in together.
When the weather is nice during Daylight Saving Time, I bicycle in and let DH drop off the kids. Then he bikes home and I pick up the kids. It's a nice system.
