Building neighborhoods with parking can lead to worse traffic, the further out you build things, the more likely people need to drive. Roads cannot become infinitely wide, so if there's a shopping center in the middle of a city, but houses spread out for tens of miles, all those people in the radius will drive, causing more traffic. If everyone is in a denser location where more trips don't need to be done with driving, people will opt out of a car, or use a car way less, thus less congestion. San Jose is mostly zoned single family homes with lots of parking, yet there's plenty of traffic. Maybe it's the ample space devoted to parking and driving that's the real problem, as it forces you to drive. I think the next step is providing more services closer to people in these upzoned areas, as well as good transit to commercial centers so they can opt out of driving entirely.
