even if supermarkets are within walking distance, if Germans are getting in their cars regularly for other reasons, that could change their supermarket shopping behavior in favor of more distant store with cheaper prices.
exactly. While living in Germany I had an expensive supermarket in walking distance, but I'd almost never go there because I used the car to go to work and stopped at a cheaper one on the way back. In Austria in the cities it's almost impossible to go by car to work because parking is incredibly expensive so most people use public transport or bikes
