As far as I can see, Uber is the problem in countries, where taxi industry is heavily regularized.
Recently Uber started its operation in Poland, in Warsaw. For 2 days that was a news, but later nobody paid much attention on it.
In Poland in order to become taxi driver one needs to fulfill a number of conditions (only people who never comitted a crime are allowed a licence, must be physically and mentally healthy) a then pass the "city knowladge" exam. Exam is obligatory only in cites larger then 100K. And that's all.
Due to competition taxi prices are kept on resonable level, so taxi companies are competing by having nicer cars, being highly available (wating for a taxi longer then 10 min is unusual), offering loyalty cards, cummulative invoicing at the end of the month, etc.
Uber can compete with lower prices - they have promised to be 20% cheaper. It is not clear however cheaper from which price - premium taxi companies (about 60 cents per kilometer) or cheap services (40 cents per kilometer).
There are other questions as well - would Uber be able to provide invoices, if not, it is not a deal for many people.
Even if I pay less (10% less?), I don't think I will risk riding with someone who might be totally unfit for the job and does not know city. Plus if something goes wrong I am not sure how Uber is going to handle that.
So, basically, Uber is one more taxi company out of 25 with fancy way of calling taxi, so there is no reason for other companies to protest.
