It is clear that the dealer was incorrect - by will or accident only he can admit. He will not want to tie up a lot of capital buying electric vehicles his customers are reluctant to buy from him, though; so both parties need incentives to change.
Essentially the law is to encourage moving away from Diesel-engined heavy-goods vehicles, in stages.
This is not radically different from policies in many other countries; although some, including the UK, are focussing presently more on cars and light vans, perhaps while alternatives for large vehicles are still being developed.
This is furthered by by tighter design, construction and testing regimes generally; and by emission-zone controls in many cities, applied typically by daily fees on those made before certain manufacturing standards came into force. The aim is to persuade using public transport, walking or cycling as much as possible, rather than private cars; but it does hit businesses and residents within the low-emission areas.
So the salient part of the New York regulations, is:
The ACT regulation requires applicable medium- and heavy-duty vehicle (M/HDV) manufacturers to sell a percentage of their total sales in New York State as zero-emission vehicles (ZEVs) starting in model year (MY) 2025 with increasing ZEV sales through MY 2035.
Transit buses, motor coaches, and emergency vehicles are exempt from the ACT regulation.
The ACT regulation does not require M/HDV fleets, owners, operators, or dealerships to purchase ZEVs, nor does it directly require dealerships to sell certain percentages of ZEVs or near zero-emission vehicles (NZEVs).
The complaints would seem based dealers and customers missing or misunderstanding that third paragraph. So not enforcing the customers' choice; but I cannot of course predict what a lawyer in the USA might read into it!
