This means that, for a short trip to Austin’s city center, you won’t need a rental car. You’ll have access to plenty of cheap and convenient options when walking isn’t possible.
On the other hand, if you have extra time and want to explore Central Texas, a rental car is the most convenient way to get to the suburbs. Fewer bus stops service far-away areas, and while ridesharing is still available, the cost of frequent long-distance rides will add up fast.
