I thought they were of concern for the effect on the global climate, in contrast to NOx, CO or HC emissions.
I would think it's academic anyway, because a vehicle that costs as much as a Ferrari isn't going to be used to commute in. Ten times the CO2 emissions from a vehicle driven 1/10th as much is a wash.
As far as weight goes, it may be huge but the article says it's just barely large enough to be classed with commercial vehicles. Wouldn't you think the biggest commercial trucks do most road damage? There's a widespread factoid that the damage is a very nonlinear function of weight, and so road taxes are allegedly misapportioned.
