~6 minutes. But the 3x/week commute to an extracurricular is 40 minutes there and 25 minutes back, so it evens out.
I rode a school bus to public school for 45 minutes each way daily for 12 years (K-11 until I had a car), so whatever guilt I feel over the long activity commute is alleviated by knowing it’s still less time in a vehicle than that.
