It is entirely possible to mass produce a basic car that is easy to work on, has cheap parts, is reliable and long-lasting, fueled by natural gas you pump from your home, that could sell for like $15k at good profit of you take dealerships out of the equation. Nobody will do it bc the entire industry besides Tesla is ZOGged. Anyone attempting it would probably wind up dead. The amount of innovation left in car design and parts production is not much. It’s all mostly figured out. If the car industry was not government run the first company to do this would own the whole thing in 20 years because you can apply this to trucks and vans etc and use most of all the same parts. 80% of the car biz is accessories, fluff and bullshit.
