Why are American cars to different compared to European?

For example, Chevy Tahoe, Dodge Ram, Ford Explorer etc. Those kind of cars are only sold in N.America and not in Europe. Why?

US cars are so big, wide and heavy! But why are they like that? Why can't you never find these kind of cars in Europe?

Also, this American "stereotype", take a look at US police cars, or the NYC yellow cabs. They have that "American" style of cars which you would NEVER find in Europe

European roadways are based on vary old roads, which tend to be narrower than North American roads. From the early days, the US was thought to be w big, wide country so a lot of that thinking carried on to making things bigger and, thus, 'better'. It is not only cars and their roads. Think trains, houses, commercial buildings. The open country in the US led to making things larger. That has changed in the last ten to twenty years as a lot of thinking has turned to reducing pollution so some things are getting smaller and more efficient.

In Europe we have much higher fuel prices.
We have smaller road that have a lot more curves.
We have had taxation on the engine capacity of cars.
We like smaller lighter cars which have good handling and much better fuel consumption.
US cars are imported in small quantities usually as personal imports.
US cars have terrible handling and very basic mechanicals and build.
The dash usually looks like it cane from a scrap wheelie bin.
US manufacturers do not want to build RHD cars for the UK or get European type approval for small sales.
They are massive barges to drive and a nightmare to park.

Short version: $0.65/liter for fuel.

We're still, as Sean says, a "big, wide country," though there are places that are becoming cramped. And this bigness and wideness makes it difficult to provide more than nominal train service, a situation which the Trump administration aspires to make worse.
