BMW vs RAM for DUI, my guess: location location location.
Demographics would likely (guess) lean towards the same type of driver in different locales. One where drinking and driving "is just a thing people do" and one where its more enforced.
It's easy because it's required. Most Americans live literal miles from grocery, Rx, or any services. Neighborhoods are mostly suburbia which has NOTHING besides houses. If you restrict driving you are condemning people to vastly inflated costs of living. It sucks and I blame the auto industries.
And actually, Americans are fairly good drivers. Because we drive a LOT. Some literally hours a day. And because we drive so much we have tens of thousands of highway fatalities a year.
Sure, doing something a lot makes you good at it. That's why racing drivers are fast on a course - practice.
But what a lot of people are doing when "driving" is not really driving - it's the act of trying to get from point A to point B while not caring how that movement actually happens. They're texting or talking to passengers or thinking about work, or what they need to buy for dinner, trying to get on with the rest of their life despite currently being at the helm of a machine capable of killing themselves and others.
Some people are out there not practicing driving, but practicing multitasking while thinking about the driving part as little as possible.
I would't say that, but considering there are cheaper and better models on the market out there now, they sure aren't being smart about their purchases.
