I think that two things have killed individuality in modern cars.
1) The corporate obsession in making all models have the corporate look, but at the same time making most SUV's look the same.
2) The inexplicable growth in SUV ownership, right up to the ridiculous barges made by Audi, Mercedes, BMW and Porsche.
And the inexorable increase in footprint, when roads stay the same, car parking spaces stay the same.....
Then people who are barely competent to drive, get a huge car with a touch screen and are incapable of doing much with it other than drive in a straight line, expecting the hoi polloi to get out of the way.
The best example of this, I watched from the top deck of a double decker in Devon, when the woman in the SUV coming the other way was so incapable of reversing that we stood for maybe fifteen minutes, as she attempted to reverse.
