Traffic talk again

I learned this week that regular traffic actually does have a name: lalu-lintas. But the driver's seem to just use the word macet which is really the word for traffic jam. Here, I'm not sure there is much difference. Here are a couple of photos to illustrate lalu-lintas/macet. Can you tell the difference?

 

In these last two shots notice how the man just puts his hand out signaling that we had better let him cross the street. That's how it's done!
