Yeah, that happens everywhere. People down here buy expensive homes 2 blocks off of Greenville Ave., one of the major nightlife neighborhoods in Dallas, and then bitch about the traffic and noise.
Then there's the fact that these Hollywoodland people bought homes in one of the most inconvenient and infuriating neighborhoods in the country. Ever tried to drive up to those homes? Seems to me that the increase in traffic should be the least of their troubles.
At the same time, I hate tourists and gawkers, and, 40 tour companies shuttling gawkers up there does seem a bit excessive. And for that matter, why do people even want to see the sign up close? It's really not particularly interesting. Go to the Griffith Observatory, do something halfway educational yet interesting, and get a much better view of the silly thing.
