While we see this specuation everywhere, I have yet to see any actual data or science that demonstrates EVs cause any extra wear compared to ICE. The narrative that EVs are much heavier is an exaggeration at best.
Lightest Tesla Model Y: 3,582 lbs
Lightest Toyota RAV 4: 3,370 lbs
Base model Subaru Forester: 3,449 lbs
Base model BMW X5: 4,540 lbs
Base model Kia Sportage Hybrid: 3,532 lbs
All the modeling I have seen actually shows that even heavier, larger consumer vehicles are not a significant source of wear.
What is? Trucking. Trucks destroy our roads.
While the gas tax seems to be both simple and fair (pay to play), and yes, EVs need to pay their fair share too...the facts show that we (drivers buying gas) are actually subsidising trucking logistics and infrastructure. To be truly fair, trucking would pay much more...and gas taxes for vehicles with lower weights per axle would be greatly reduced or nearly eliminated, but that cost would be passed on to consumers with added costs for all truck freight passed through to the products they move.
We would all still be paying, but more fairly, with higher costs on products, and less consumer fuel taxes. We would have a consumption tax on things moved via truck, not on how many gallons of fuel or KW of power we buy.
I don't for a minute think this would be easy or popular to enact. But the point is, EVs are not the problem, heavy trucks are.
Most who propose high taxes on EVs due to "excessive wear and damage to roads" are using a straw man argument to support ICE and disincentivize and even demonize EVs.
