The biggest problem in LA is the traffic, plus that you need a car to go anywhere.
Try to go on average day from Griffith Park(Observatory in the picture) to Santa Monica(surfing). You will hate your life.
People who live in LA are kinda used to crazy traffic, but if your value your time, LA is not the place to be
Not just because of the time. But because there is hardly anywhere to live that isn't filled with cars AND walkable.
It's nice that the city has become a lot more walkable - but it's not that enjoyable walking alongside what is basically a highway - I.E. Hollywood, Sunset, and Santa Monica Blvd.
It's such a shame that the city with some of the best weather in the country, and that would otherwise be great for biking, is the city with one of the strongest car cultures in the world.
But for most people in LA, it is not the case.
