In Iowa, if you say something is 10 miles away, that usually correlates to a 10 minute(ish) drive. In LA, ten miles usually equates to a 90 minute drive, in my experience.
Traffic wasn't even bad but several years ago I got picked up at the airport and we were going straight to a Dodgers game, which was 'just a short drive' according to who picked me up.
It was two hours.
