If I bought a home on the far end of this road thinking I could buy a hybrid or electric car and use it on the toll road, and then suddenly they take that away and start charging $30 each way, I'd be really upset.

Whether the expectation that this road would remain open to hybrid cars is a _reasonable_ one is an interesting question. I'm not aware of similar changes (hybrids losing their exemption) in other road systems, but I don't exactly read transit-hawk blogs.
