1) Smart Grid is the devil. It benefits only the utilities; no one has come up with anything better than feeble hand-wave benefits to the consumer. Internal "smart gridding" of the home so usage per appliance could be tracked would help, but is of no interest to the utilities. They just want to be able to cut off power where and when convenient, to reduce peak load requirements. Bah.

2)Tesla has gone with Solar City in offering free power to all Model S owners (on intercity freeways, etc.) using the best model: power the cars with Superchargers connected to the grid, and generate excess solar power to sell back to the utilities (i.e., more, overall, than the cars draw). Brilliant!

Well, the benefit to consumers is that the grid will go dark less often. Since we aren't used to this happening, I think we underestimate that benefit. Alternatively, we could pay more so that they could just install more capacity, but that's not how things seem to work in the real world.

It certainly serves as extra capacity, but if the FIT is > grid price, consumers are paying too much for it. As is the case with virtually all solar power, except in a few special circumstances of no economic importance.
