But the subject of OP primarily hurts families with multiple children, but even if it somehow did cause enough advocacy and lobbying, creating better public transit would take decades, at which point the parents would no longer be paying for insurance for their children.
The alternative is doing nothing and hurting people right now. The people who rely on public transportation most are poorer people. Something, eventually, has to be done because the path we're on is destructive. It's getting to the point where it's difficult to go just about anywhere. We're running out of space to put the roads.
