Which public transport system is your assumption based on? I used many public transport systems (Mostly Europe and Asia) and usually you don't have to account for schedules if you are in a city as trains / subways / busses just arrive every few minutes. The rare case where you have to take a lot of luggage can always be covered by taxis. In no way is that more annoying than finding parking, sitting in traffic, taking your car to maintenance etc.
