If all three options were practical, which would be your preference? As in, if your work had all the amenities for cycling (bicycle storage, showers, etc), the bus stops conveniently close to your work, and there was sufficient parking, and each mode would get you there in a reasonable amount of time, which would you choose?

For example, here's my previous commute:

• bike - 30-40 min, 100% separated bike path, have shower at work and indoor space for my bike
• bus - 30-40 min, one transfer (<5 min wait), and stops right in front of my work
• car - 20-30 min drive, depending on traffic, outdoor parking

The car is a little bit faster, but not dramatically so. If 30-40 min cycling is too much, change the thought experiment down 10 min for each option.

For me, my preferences are:

1. cycling - get exercise and commute done at the same time
2. transit - can do other stuff while commuting, like read a book, play video games, etc
3. car - a bit faster and more flexible

I don't like driving, but I'll do it if the benefits outweigh my preference.
