Adding more lanes means you invite more traffic on the roads, which means you’ll eventually have more traffic on it and have the same problem later.

But to make the problem worse, now you’ll have to maintain all those extra roads, sucking future money from future projects.

Or, you could build up non-car transportation infrastructure, which would be more efficient at moving people and freight, and relieve some usage, wear, and tear on the highways.

If you love your car, encourage using tax money to be spent on public transportation.
