> Salient example is a Tesla model S, which have a curb weight of 2.1 metric tons in standard configuration [1], while comparable gasoline-powered sedan weights in at approximately 1.5 metric tons [2]. That means that applying formula above, "average", electric car causes 3.6 times more road wear than "average" CO2-belching one, just due to being 40% heavier while having same number of axles.

The comparison doesn't hold, the Model S is a full-sized sedan, the 3-series is a compact. The Model S is somewhere between the 5-Series and the 7-Series, closer to the 7-Series than the 5.

Either way, both EV and ICE car road wear is completely dwarfed by trucks.

It is a moot point. Having seen (but not driven) model S, I can't say it looks big enough to warrant comparison to a 7-series, and even then latter is 1800kg [0], so Model S is still 17% heavier or causing 1.85 times road wear.

Point about trucks stands of course, as you've pointed in the other comment. 3-4 orders of magnitude more road wear - that's crazy! I wonder how does that translates to truck road taxes.
