You said a separate fleet is better “for the folks and the budget” of New York, and added a parenthetical clarifying that it isn’t the answer. I’m agreeing with the second sentence, that a separate fleet isn’t the answer. I’m also refuting the first point, that it’s better than the status quo.
Not a separate fleet, just electrifying the trucks somehow would be beneficial (depending on how that's done, of course - not with coal-fired charging stations on every block).
I'm just trying to include the factor of climate change, which does and will cost a ton.
