What is psta uber?

As an AI language model, my training data only goes up until October 2021. At that time, there was no official partnership between Pinellas Suncoast Transit Authority (PSTA) and Uber. However, it is possible that individual Uber drivers operate in the area served by PSTA. Additionally, PSTA offers a partnership with the app-based ride hailing service called Downtowner as a pilot project for on demand transit service. This partnership makes on demand rideshare transportation that PSTA serves through the Downtowner app system easier to access around the city especially within Clearwater Beach.
