If your household has more than two vehicles, you can add up to three vehicles to the One Car Challenge. We expect most households will add just one or two.
How to add another vehicle
1. Open the app and tap Menu → Vehicles.
2. Tap Add Vehicle.
3. Enter the make, model, year, and license plate.
4. Choose Photo or Auto-Submit for that specific vehicle.
Each vehicle can use a different reporting method — for example, one car on Auto-Submit and a second on Photo.
Why is there a limit of three?
The pilot is for households testing a "one less car" lifestyle, not large vehicle fleets. Three is enough for most multi-car households while keeping the pilot honest.
How does the ≤3 miles/week rule apply with multiple cars?
The rule applies per vehicle, per week. Each car you add must stay under 3 miles in any given week to earn that week's reward. You can earn rewards for multiple parked cars in the same week.
Removing a vehicle
Open the vehicle in Vehicle Details and tap Remove. Any rewards already earned for that vehicle stay in your balance.
