I was staying at a hotel with a colleague last week and the front desk recommended a restaurant for dinner. Per Yahoo Maps, it was 0.43 miles away.

I grabbed my wallet and started to head out on foot, but my colleague reached for his car keys. I told him it we might as well walk because it would be only 10 minutes, and he looked at me like I was crazy.

So this got me thinking, what is your threshold for walk vs. drive? Mine is around 3/4 of a mile. Maybe 1 mile if I'm in a pedestrian-friendly downtown area, or if I'm feeling in the mood for some exercise. If I don't have a car and I'm relying on transit, then perhaps a bit more.
