Yeah but you should be able to intuit that the country with no alternatives and a car culture where everyone gets a license easily; The rate of drunk driving is probably higher than other countries.
Like I've been places in this country where the bars were so sustained by drunk driving that the police would wait outside and pick off cars like seagulls to turtle hatchlings unto the sea. It was systemically expected with local cops pulling me over multiple times and one even calling me "the sober guy" as he waved me off in disgust, it being so unexpected that any car would actually have a real designated driver.
Sure you might do some science and find something surprising, that's why we do it, but in a case like this a normal person should have reasonable faith in their intuition and not require a masters thesis before making up their mind that in a country that actually encourages drunk driving, rates of drunk driving are higher than most other places and mot average.
Maybe I'm misunderstanding and you're saying they gather statistics differently but nothing you"ve said previous to your last post indicates that with much clarity.
