Which has more momentum: a large parked car or a slow moving feather?

Slow moving feather

The parked car has 0 velocity since it is stationary. The momentum of the car is 0 because momentum = mass*velocity.

On the other hand, the feather is moving, so its velocity is some positive value. Even if it's a small velocity value and the mass of the feather is small, the two will multiply to some positive momentum which is larger than 0.

So the feather has larger momentum compared to the parked car.
