I prefer to ride trains/subways when I travel. It’s generally a great way to avoid traffic. It can be more affordable than Uber or taxis. And, it gives me a feel for the city that I don’t get when I’m riding around in a car.

Public transportation is a great option in Sydney. There’s a clean, efficient train system and a comprehensive ferry system which provides great views of the city. Both are affordable.
