around 65 million new cars are sold per year. toyota/vw do 10m each year each.
sales of super sports cars (ferrari, mclaren, lamborghini) combined are less than 20k units per year.
so, only one in 3.000 cars is a super sports car. additionally those cars usually do extremly low mileage of less than 1000km per year. you'd be very hard pressed to find a used ferrari with more than 30k kilometers, even when looking for very old ones
so if we combine the rough numbers (1/3000 the volume, 1/10 the mileage, 5 times the consumption) we arrive at the conclusion that only 0.016% of the car emissions come from super sports cars. the number is so low it is basically meaningless, especially since private transport is not a huge percentage of emissions to begin with. for the climate it would be better to upgrade a single old tanker or steel factory than to outlaw combustion V12 sports cars. forcing niche manufacturers to EV-only is not about the climate, it is about jealousy and malevolence, as is most of politics.
