One important difference, I believe, is that your can is effectively sealed.
As soon as the vapors reach equilibrium with the fuel, it both stops
evaporating, and stops absorbing moisture from the air.

Most modern cars are sealed as well, but many older ones (as well as
tractors, boat motors, lawnmowers, etc.) are not.
