I had two grocery stores in 5 minute walking distance. I had one store with more stuff, think also basic electronics, kitchenware, home appliances etc, in one station with the inner city train that was a 5 minute walk from my flat.

For years i did my groceries taking the train and i fail to see the problem. Just having to walk to the parking lot, get my car, drive to the store i can reach by train, then park there would have taken me twice as long even without traffic.

In inner cities cars are a liability for everyone including their driver.
