People who have never been to L.A. really have no idea how insanely huge it is. Driving to my apartment from the start of city (before you even get to L.A. county) and having the city just keep going and going and going for two hours and not because of traffic jams is something you have to experience to truly understand.
as an expert on the topic of los angeles (i spent 3 days there, many years ago), i can confirm that it is exactly the kind of city where every drive takes 1 hour. if you have to get on the highway to go somewhere, you better cancel your plans for the evening because your new plan is to sit in traffic forever.
