A 40 tonne lorry damages the motorway as much as 1000 passenger cars.

According to an old and well-attested empirical formula, road damage is proportional to the fourth power of vehicle weight. So if we make the pessimistic assumption that those passenger cars weigh 2 tons (pretend they’re all SUV-sized EVs), then the damage ratio is on the order of (404)/(24), which means your 40-ton lorry does as much damage as 160,000 cars.
