Your horse comparison doesn't work, no matter how many examples you try to show. If we didn't have a road system, it may work, but that was 100+ years ago that any comparison would be valid.
What we are talking about is changing the propulsion mode of the automobile, not how we transport people and goods. Electric may be the future, but it is coming faster than the actual demand for it is growing. It is being forced as the new normal before being normal. In Minnesota, we sell 2,000 electric vehicles a year, but will be mandated to have 19,000 of them sitting on dealer lots in 2024. That will increase the cost of every IC vehicle on the lots to cover the money the dealer pays for those ev's that aren't being sold. It will also increase the cost of used vehicles, much the same way the chip shortage is raising new and used car pricing. Demand isn't there yet. Even in the bluest of blue states where they sell many more. I know Chicago has a ton of them, but they are a city of 2.8M people, so the greater numbers are to be expected.
What is the total percentage of EV's on the road today? Please show me those numbers, it will show how far off the demand is for these cars.
And if the younger people in urban areas don't want to even buy a car, that reduces the demand even more.
