Right again. But if they had not permitted all the development in all those random places, the traffic would not have gotten so bad.
And once the traffic is bad, it stays bad, forever. Adding a lane helps for maybe a day and then more cars flood in from elsewhere to fill that temporary void. Cars are wonderful to use, but terrible when other people use them. Mass transit for all the other people, and I stay in my car on empty roads is the best solution.
If you really want most people to take mass transit, you will have to start doing so yourself to set the example.
