Eli5 How are carpool lanes supposed to help traffic? It seems like having another lane open to everyone would make things better?

I live in Los Angeles, and we have some of the worst traffic in the country. I’ve seen that one reason for carpool lanes is to help traffic congestion, but I don’t understand since it seems traffic could be a lot better if we could all use every lane.

Why do we still use carpool lanes? Wouldn’t it drastically help our traffic to open all lanes?

Look up induced demand. Adding lanes does not solve traffic and usually makes things worse in the long run . Look at cities where they just constantly add lanes instead of promoting public transit, they have horrid traffic with massive highways. LA is one of the cities where they constantly add more lanes, does it help?

Examples of such are the Katy freeway and the 401 in Canada.

Ps I realize I misread the post but my response is still valid in the sense that you want to promote more efficient lane usage before letting people go ham on them
