Because it is ridiculous. That's like arguing guns should be banned because they pollute the air when fired. The so-called pollution from guns is tiny when contrasted against discharges into the atmosphere from factories and aircraft. It is not a battle that needs to be fought.
There are many haters of EVs, and they're throwing everything negative against the wall hoping it sticks and will make them go away. Same as what liberal Democrats are doing to Trump.
The truth is that moving freight on roads causes much of the tire pollution. Did you know that ICE vehicles create a lot of pollution on roads from the wear on brakes? Not much pollution from EV use of brakes, because they use regenerative charging instead of grinding brake calipers and pads in order to slow the vehicle. Yet you don't see this factored into so-called "facts" in comparison between ICE and EV pollution.
The argument about tires on ICE and EVs is ridiculous. What I've always said, is that ICE vehicles will be around a long time, perhaps forever, and EVs will not penetrate more than 40 percent of the market. And that is not because of tires, but mainly due to horsepower, range, and electrical supply reasons. I much prefer long distance hauling with my ICE truck, same as most people.
Electric supply is the elephant in the room.
I have seen zero evidence of any serious effort to increase regional or national electric supply.
Since it can take a decade or longer to add major new supply that makes this a deal killer for decades to come.
