Yes, via trespassing laws.
(Essentially, if you park in a hybrid space with a non-hybrid, the property owner or their agent can request that you leave their property. If you do not do so, you are now trespassing.)

If a person is going to drive a big SUV anyway, there is a greater impact overall if it's a hybrid than if the person driving a small car switches to a small hybrid.

And this is why distance-per-fuel measurements (mi/gal, km/l) are rather poor, and fuel-per-distance measurements (l/100 km, gal/100 mi) make more sense. Distance-per-fuel magnifies small improvements to an already efficient vehicle, and minimizes large improvements to an inefficient vehicle.
