Well, that’s not necessarily true. Uber can offer chauffeur services at any price, but as soon as they pick people off of the streets, it becomes a taxi service, which has the maximum fare limitation. Well, at least according to what I could find about the rules and regulations in Kiel.

You know when booking the trip what the cost is, it's not a mystery.

> the fare is regulated - no matter the demand, the area of the source or destination

Does Germany not have supply problems caused by this policy?

I know it's impossible to get a cab in Toronto on New Year's, whether you're coming home from a party or your wife is going into labour. I'd personally rather know for sure there is a ride available if I need it than be stranded by the side of the road because nobody is allowed to take my money.

There are almost never supply problems, but this is to make sure taxi companies don't scam people as it's usual in southern europe.
