I'm certain that's true; LA has a helluva reputation. I just felt (dare I say this on a forum about road trips!?) that I was caught between feeling I needed to rely on the car because of LA's gargantuan size, and finding that driving it in LA's frantic traffic took too much of my attention away from experiencing much of what was around me.
By contrast, the previous week in (the physically smaller) San Francisco, walking everywhere or taking the cable cars—with someone else "driving" them—seemed to serve up a better means of taking in the sights, sounds, smells…
I guess it's just a question of understanding the city a little better; after all my years in London I shouldn't have been so phased by a big city but I kinda developed tunnel vision and spent too much time staring at the fender in front of me, worrying that I was wasting my lamentably short time there.
