I have a conspiracy theory take on traditional manufacturers being so anti-EV.
Basically the primary differentiator between car companies and the primary barrier to entry in the combustion vehicle business is the engine, especially in the US. Look at the marketing, horsepower and torque are always the topline numbers. Zero to sixty and quarter mile drag races are the favored metrics. Each company spent decades perfecting the engines and the majority of the engineering effort goes into them. Even the transmissions get second fiddle status.
But now EVs come along and the electric motors are commodity parts that are already well optimized. There's little one company can do to make the motor significantly better. Battery tech is cutthroat and also largely outside of the car company's scope, although Tesla does more than other car companies with their megafactories and experiments with oversized cells. If EVs become popular there's little to stop competition from sprouting up everywhere and killing profitability for the legacy auto manufacturers.
That's one way of seeing it, but the fact is that automobile parts are already nearly commodity parts. The wall that stops automaker upstarts in their tracks is the need for safety testing and approval from the US DOT.
Even if you had the chutzpah to get all of the materials together for a fleet of vehicles, you have to spend big cash and grease a lot of palms to get a vehicle you make certified. It takes years and millions of dollars to get to the 1st sellable vehicle.
This is a portion of why BYD, for instance, isn't selling in America.
There are other reasons of course, but one of them is the millions and millions of dollars you're putting at risk just to potentially be told "No" by the government.
