Have you never bought insurance before? Car insurance at least has always been based on assumptions from a bunch of data about you.
There are overall considerations (eg. Age of the driver, cat accident history etc) but was never about how I drive my car.
You said "It used to be that you'd get a high insurance fee only if you cause incidents or damage".
I'm saying that no, Insurance cost has always been based on factors other than just accident history. And you seem to be agreeing with me.
Driving style was never (at least from where I'm from) a factor that determines the fees of the insurance
