7 days defying car culture is a looong stretch. How about "Car Light?" The motor-vation for being motorless: you score like a pyramid. Each day you do without the car is going to build on the previous (see the table for categories).

Not to challenge the PansyMath folks, but you get 1 point for one day, 3 for 2, 6 points for 3 days, 10 for four, 15 for 5, 21 for six... and jump to 30 for a solimmd week.

Not being the Control Free-K, if you end up going somehwere with somebody but they were going *anyway,* you're still car-free. All the other, oh, 12-passengers-and-up thingies hold true. If you rent a car, that isn't car-light.
