Expect some local attention of your fine is above 50€.
Regarding the moral issues of paying speeding tickets, read this:

The admin fee at Sixt is 18.50€ or lower:
I 3.
The lessee and his vicarious agents shall be liable without limitation for the breaches of any statutory provisions, particularly for traffic and administrative offences, committed by them during the rental period. This also applies to breaches of statutory provisions or other regulations by the lessee committed just as/at the time when the rental period ends, such as e.g. leaving a vehicle in payable parking lots without paying the appropriate charge, leaving the vehicle in no-parking zones or suchlike. The lessee shall indemnify the lessor against any and all penalty and warning fines, fees and other costs, levied by the authorities or other bodies from the lessor because of any such breaches. As compensation for the lessor's administrative costs incurred in handling enquiries put to it by the prosecution authorities or other third parties in order to investigate administrative offences, criminal offences or any nuisance committed during the rental period, the lessor shall receive from the lessee a flat-rate amount of EUR 18.50 (incl. VAT) for each such enquiry, unless the lessee proves that the lessor incurred lower costs and/or loss; the lessor shall be at liberty to assert greater damages or loss.
A lower 10€ fine may not be followed up, more serious violations will most certainly get the police into play.
