Yep, there are some areas of Uber that need to be better regulated, as Icey and HM mentioned above. Anecdotally, the drivers I’ve spoken to (all of them, I’m a latte sipping, leftie SJW from the inner suburbs), are happy with how Uber treats them. There’s a lot of former cabbies who are making more from Ubering than from cabbing.
Uber is filling a hole and it’s legal and above board, mainly because the governments in most states dropped the ball, either directly in their regulating handling of the taxi industry, or in related areas such as public transport, road infrastructure and the like. Taxi regulatory boards also seem to be a law unto themselves and in no way help the perception of their industry and its members.
As a user, I find Uber to provide the better service by the length of Flemington straight. Quicker, cleaner, friendlier, cheaper, easier to book, easier to pay.
