I don’t think it would be productive (or fair) to send a message of “your eco-friendly car is welcome”, when the real concern is traffic/space and any “green car bonus” might disappear on pretty short notice.
Incentivizing eco-friendly cars is great in general, but I think the two concerns in this case are best addressed separately.
In fact, for a geography like Manhattan, prioritizing public transport and small transport (bikes and scooters) would go a long way in improving congestion and conditions in general.
