Licence, VAT and the airport kerb.
Germany has no car tolls on its Autobahns and no congestion charge in any city. What shapes a Cologne fare is the licence the car runs under, the rate of VAT it pays and the airport's short-stay tariff.
Every RYDES car in Cologne is a Mietwagen, licensed under section 49(4) of the Personenbeförderungsgesetz. The rule is simple: the booking must reach the operator's business seat before the trip, the car may not be hailed or wait at a taxi rank, and after each journey it returns to base unless the next booking is already in (the Rückkehrpflicht). The licence comes from the City of Cologne, and the driver holds the Fahrerlaubnis zur Fahrgastbeförderung, the passenger transport permit known as the P-Schein; since 2021 new applicants prove professional competence rather than local street knowledge. For you this means the car is always pre-booked, the price is agreed before you get in, and the chauffeur is coming for you by name. It is also why you will never find a RYDES car on the street. RYDES arranges the trip; the licensed chauffeur operator carries it out.
The rules are enforced. In 2025 the city's Ordnungsamt checked 185 company premises and ran 730 road checks, finding 304 return-to-base violations and opening 366 fine proceedings. Since 1 November 2025 it has matched data with Uber and Bolt, 140 non-compliant vehicles were taken off platforms during 2025, and more checks are planned for 2026. Separately, the city set a Mietwagen minimum fare, no more than 20 percent below the taxi tariff, from 1 June 2026. On 24 July 2026 the Verwaltungsgericht Köln (18 L 1226/26) suspended it in interim proceedings as likely unlawful, and an appeal is possible. Its status stays open while the case continues. RYDES fares are fixed in advance either way.
Taxis in Germany pay VAT at the reduced 7 percent rate, which helps on short local fares. Mietwagen pay the standard 19 percent, as the Federal Fiscal Court (BFH) confirmed in 2014, and that 19 percent is inside every RYDES price. The CGN Kiss & Fly or car park charge for your pickup is treated as an airport fee and included too. Inside the Umweltzone, which since October 2019 also covers Rodenkirchen, Lindenthal, Ehrenfeld and parts of Nippes, Mülheim and Kalk, cars need the green sticker, and every operator's car carries it. Cologne has no city-wide diesel ban.
Routing is the operator's decision rather than yours: a chauffeur heading from CGN to Deutz on a fair morning may stay on the right bank rather than crossing the Rhine twice, and neither choice changes what you were quoted.
