I really want to dislike Uber because I'm generally much in favor of locally-operated public services rather than a big foreign corporation, but man, taxis really make it hard.
In my country (Spain) there can't be more than 1 Uber (or similar) per 30 taxis by law (obviously pushed by the taxi lobby). That's actually enforced, at least in my region (I think in some regions, like Madrid, it's not). Additionally, in my region Ubers are further nerfed by requiring booking 15 minutes or more in advance and not allowing trips inside of a city, but they just disregard that law and at the moment it doesn't seem to be actually enforced, although taxis are protesting a lot about it so it might be in the future.
Normally I would be indignant at a foreign big corp disregarding laws, but it's hard not to support Uber when taxis are clearly not enough to meet demand (sometimes you need to wait half an hour for one, in a small city where if you are fit you get to most places walking in that time anyway. If I want a taxi it's because I'm in a hurry and walking or taking a bus won't cut it, if I have to wait 30 minutes for a taxi it becomes useless) and they constantly push not only to limit the number of Ubers, but also the number of taxis themselves. They prefer to be guaranteed to always have customers waiting and see the taximeter numbers go up constantly, and screw the people who have to put up with a terrible quality of service because they don't meet demand. In the past I used to take a taxi to the train station if I'd rather work some more instead of stopping 30 minutes earlier to take the bus, now I don't even bother because you might need the same time to go by taxi than by bus due to scarcity of taxis.
Add to that that many taxi drivers are rude, and many drive Dacias which are the cheapest low-end car here... come on, I'm not saying they should be luxury cars, but you are serving customers in a car that is your whole means of production, your image and your calling card, and that will be amortized very fast, and you go for the absolute cheapest that you can find in the market? What does that say about your care for the customer?
I take Ubers whenever I can (which is also seldom, because obviously with the 1 to 30 rule they are even further than taxis from meeting demand) because taxis really go the extra mile to make me hate them.
