What are you talking about? Ford has better battery chemistry, Chevy has better interiors, Rivian makes a better truck, and those are just American brands.
Took Ford 4 years of production to swap to heat pump, Chevy's tech is completely laughable it would be a 500% improvement if they just removed the screen, and did carplay only
Frankly I don't need my car to have a gaming system bolted to it. I prefer carplay for music and navigation, and physical buttons for climate control. I think a lot of 'high tech' Tesla design decisions are actively hostile to the driving experience.
Carplay can be done without a screen just add GPS arrows and track info to an HUD.
That is part of what annoys me about legacy Auto EVs they try and fail to compete with Tesla, and just give their horrendous infotainment larger screens. If I could option those away I'd seriously prefer that. I care more about what makes the car go.. If I could exchange the screen for more range then that'd be for me.
Another thing that bothers me is packaging. Gigacasting just makes for a better overall car whereas a lot of legacy Auto stuff is conversions of ICE platforms.
There's loads of electric vehicles on the market in the US with similar tech to the Tesla. What tech do you want anyway, the most useful thing that Tesla has a reverse charging which is not at all unique.
