It’s true but the author should check the fourth power law. Most of the road wear comes from the heavyweight vehicles, the trucks. The little weight increase on personal vehicles isn’t that bad for the roads.
Making lightweight electric cars is also possible, the old bmw i3 was light, but it’s more expensive.

- ksplicer 3y agoOne aspect that isn't discussed much is that the heavier vehicles do put appreciably greater wear on tires. Since as much as 70% of microplastics in the environment are from tire wear any increase may have a pretty alarming impact on the environment. There is no car based solution for the environment.
