UPDATE: The SPD told a paper on Monday that they will not agree to law reforms that entail "backdoor costs" to German motorists when road tolls come into affect on Autobahns.
Daimler and Deutsche Telekom may have to strike a billion-euro compensation deal with the government over the disastrous introduction of a truck road toll in Germany more than six years ago.
Germany needs to institute a time- and location-dependent toll system on all streets to help cut the costs of too much traffic, said Hans-Werner Sinn, head of the influential Ifo economics institute, in an article published on Saturday.
