Though now I just buy groceries online and have them delivered
... which requires more road use than people stopping by the store on the way home. (Round trip vs. one way)Though in my case, I usually alternate between bus and bike to work, so if I did drive to the store, it'd be a round trip. If I bike to the store, it means a round-trip from home since I usually have one or 2 commuter panniers on the bike when I go to work, and don't want to haul the empty trailer all the way to work and back.
Does it? A truck uses around the same road space as a car
Well, if you ignore fuel consumption, pollution, and parking impact. Anyway... so if it removes one person in the neighborhood's round trip to the store
No, I was referring to the specific "on my way home" use case you referred to... which is the typical case. If you stop by the store on the way home, you aren't adding a trip in either direction. Having delivery adds two trips, from and to. Two trips vs. zero.I don't think you read my entire comment: "When I lived in an area where I could commute by subway, I had a full service grocery store and several smaller specialty markets (a produce market, a butcher and a bakery) on my way home"
I was referring to the comment asking how to shop by subway -- the answer is to shop in smaller increments, but now that I bus/bike to work and no longer walk past a grocery store on my way home, I just have groceries delivered.
Your answer seems to be saying that the answer to shopping on the subway is to not take the subway and drive to work and stop at the store on the way home.
When I lived in an area where I could commute by subway, I had a full service grocery store and several smaller specialty markets (a produce market, a butcher and a bakery) on my way home (well I had to get out one stop early to pass the butcher). I see plenty of parents with kids on the subway -- though none of them have the full-size strollers you see coming out of the backs of SUVs.
So instead of making one large shopping trip every week or two, I'd stop several times a week on my way home.
Though now I just buy groceries online and have them delivered, in the rare cases where I do want to go to the supermarket, I take my bike.
