California's government is not exactly famous for keeping their word to the citizens.
We will see. I hope it's not cut for good, but you cannot predict what Sacramento will do.
As far as the Low-Income program, the table is based on # of dependents and household income. It's <$73,800k for a family of 4.
Do not confuse this with High Income caps. That's different. In fact, low income is eligible for higher rebates than normal income. High income gets no rebates.
$8 million won't go far at $3500 to $7000 a pop (low income rebate range). About 2,000 cars max in a state of nearly 40,000,000 people.
PS
@Waiting4M3 - RTFM about the rebates, don't guess. You are just going to piss off folk by posting crap that isn't true.
