Not in Denmark. It was only ever cheaper for a while, while the investors sank money into choking out competition, which they failed at.
> using an app to reserve a taxi
Unlike in Germany, Uber actually brought apps to taxi companies in Denmark, before Uber got banned.
> making the process and the product reliable, customer-friendly and consistent
Uber was never more reliable or consistent than traditional taxis in Denmark. More friendly, sure, full-time career taxi drivers are more socially distant.
I once waited for an Uber that was “just around the corner”, except the blip on the screen with a name and a picture was just a visualisation, there was no car. The street it was supposedly stuck in traffic on was empty.
The app was simply lying to me, hoping a car would become available before I tried another taxi service.
Hardly an improvement. Just cheaper for reasons that were not possible long-term or fair to the drivers (not sufficiently factoring in the cost and risk of the car).
