Overlooked in a lot of discussion of the CO2 impact of Tesla vs ICE is the effect of the added weight of the batteries on the amount of road damage a car will cause. A study in the 1950's showed that road damage is proportional to the third power of the axle weight of the car. If the Tesla weights 1/3 more that a similar ICE vehicle it will cause (4/3)^3 or about 3 times as much damage to the road a similar ICE. Replacing the fleet of ICE cars with Tesla type cars would lead to the road being replaced 3 times as often. Note concrete production is large CO2 emitter.
