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?

The only real solution to traffic is automated cars.

The faster we get those on the road and the fewer human driven cars the less traffic problems there will be.

Once automated cars are the only cars, you can actually apply and enforce blanket policies across all cars effectively.

They don’t. They are an incentive for you to carpool, saving YOU and your passengers time while also being more green.

the more lanes you add the more traffic you are going to bring to the road, which in turn just makes congestion that much worse. there is many videos on YouTube that explain this.

what would absolutly help is to bring public transit back into wide spread use

If you reduce the number of vehicles on the road, you reduce the amount of traffic.

As an incentive to try and stop single-rider vehicles, the car pool lanes allow multiple-rider vehicles.

Some people have mentioned it encourages carpooling, but the real reason is that it makes traffic worse, which over time will encourage people to take alternative methods of transport

If you build more lanes, travel times reduce, so less people carpool, so traffic increases, so travel times worsen, often worse than before
