Would you say you could rely on them as a means of transportation or are they still difficult to come by?
Announced today they are putting their charges up by 10%
As per my post in your question regarding Uber in Paris. Uber is no longer reliable. Surge pricing, cancellation due to a more lucrative fare and a history of unauthorised drivers means that I avoid Uber now.
I wouldn’t use them. Flaky.
In London - for me personally, I dont know why you would use Uber. Transport in London is super, and if I need a taxi, I'm happy to take a black cab. What the others have said regarding pricing et al holds true.
The very same could be said of Paris.
