Good news:
the municipality of Eindhoven has adopted a new parking regulation which regulates the issuing of shared car parks.
For €102,-per year per car we can rent a permanent car park for our shared cars (regulation on the levy and recovery of parking taxes 2019; Tariff table F. 3, Gemeente Blad 270372, 17 December 2018)
Hopefully we can also arrange for the placement of a private charging station with electricity from a private electricity connection. That would settle it all!
