I know that American cars are supposed to be bigger than
European cars, But 3 metres is [almost] 10 feet. What size
are the the car windows you can resolve things to this scale
through? :->

3 centimetre resolution sounds more reasonable, but this is
close to the minimum being mentioned by previous posters.
