Is v2l really that big a deal to people? The house side of the system is VERY expensive. Light loads ARE a big deal, but can be handled out of a standard outlet (like Ford's ProPowerOnboard thing)
They can implement V2L in the exact same way they were going to do it with the CCS connector. CCS did not specify a single way to do V2L, and current implementations by Hyundai, Ford, etc. are not standardized or brand-interoperable.
While I would prefer an interoperable V2L standard, NACS is not a change for the worse in that regard. It does not prevent manufacturers from implementing whatever V2L system they wish on top of the NACS connector.
EDIT: I was wrong. Please see below for correction.
ORIGINAL COMMENT: That's not true. You can buy a generic Lectron V2L unit that will work for both Hyundai and Ford and other brands. It's based on J1772 and it's a simple adapter.
Because they offer free charging for financially literate customers. The customers are going to abuse it. In their typical corporate fashion, they don't use languages to communicate on that topic.
