There is no brake on rents. The market regulates the price. Not everyone has to live and work in absolutely high-priced city locations. However, traffic and housing concepts should be created in the vicinity of conurbations to meet the demand for housing in beautiful surroundings at attractive prices. This requires new concepts to connect rural areas to the conurbations with high-speed trains and public transport in such close proximity that daily travel times remain short. Integration of flying electric taxis will expand the catchment area even further.
