That's not how liability works, not either morally or (IANAL) legally.

Because you didn't find out it was a bear trap until after you stepped on it?

Ah, yes. The old story of the one-footed man who didn't take the car.

Well I would feel slightly irate if I had to find out about the bear trap before I decide I don’t want the car.

That’s fine, you can leave the car, but you’ve already lost your foot. Why do you find this confusing?

You discover it’s a bear trap not before you try to pull out from the parking lot.
