The first article you cite does not show that Uber and Lyft made traffic worse. The study simply states that they account for 14% of traffic. Fewer personal cars, less cruising for parking, and ability to reliably use Uber/Lyft for the last mile in conjunction with public transit could easily make traffic better overall. The second link is also not as clear as you make it seem. The growth in car-free and car-light households is exceeding the growth of the general population. Those cities are notable as they were the first to get Uber/Lyft.
