You'd be surprised. Cars will burn a sign, but they'll stop dead when they see a person holding a sign.

You also have to watch for the pedestrians walking around and so on. It's actually a lot more involved than you think.

I did it a few times. Not hard, but it does matter a lot, and definitely not pointless.

I can't help but ask, how about a wax sculpture? hehe :)

But, yeah you have a point.
