Traffic compounds the problems of public transit, but public transit is really bad even on its own. It's slow on its own, total cost is high, it's inflexible for many purposes, it doesn't respond to changes in the city, it's run monolithically, it's not aligned with its customers (customers are a liability), it's designed to encourage points of failure. It has such a multitude of problems, making cars less attractive won't go far to making public transit more attractive.
