There are three grocery stores within a 15-minute walk of my house. Two of them are next to the nearest subway stop; they add no more to my commute than walking through a parking lot would add to yours. The subway gets me to many useful places in 30 minutes. My time is valuable, and I spend none of it stuck in traffic or looking for parking. Advocating for density means that more people have the option of living this way.
