Sure, in general, but this is why I wrote "to me" as in I don't care about he price difference. (Which, btw, in Stockholm is not very significant.) My account was simply meant as an anecdote to support the parent comment, that a local alternative can compete quite successfully. In my case, the convenience was key, not cost. That said, if they were consistently half the price of regular taxis I might reconsider. But only
might because it's unclear to me who's responsible if things go missing during my trip, if there's an accident or the likes. With the traditional cab companies in Stockholm it's very clear who to turn to.
But I agree with you in the general case, certainly.
