Yes, but you are one of likely very few with that experience available.
You are beholden to the bus schedule. Your choice of where to live greatly affects your commute. You have to combine multiple transportation options. If the weather is bad, you are exposed to the elements.
Uber remedies all of the above, and yes, for a price, but not wholly unreasonable. Sure there will always be less expensive options, but Uber appears to be quite reasonable when you consider the big picture. Is it sustainable? They'll show us.
It also has the neat feature of being able to continuously optimise and become more efficient. Most other public transportation does not, is heavily subsidized, and extremely difficult to change.
