It’s not a giant conspiracy, it’s just that cars are extremely inefficient transportation and are unsustainable, and dangerous. The goal should be reducing car usage to as little as possible and what’s left should be electric. I don’t think your horse and buggy analogy is applicable here because you’re the one who’s advocating for a nearly 100 year old technology over modern design and infrastructure principles.

Personally I’d rather have an electric car than a gas car but I’d rather not have to own a car at all. I’d rather have safe, walkability with public transit so robust that I can get anywhere I need to go without checking a schedule.
