Millions of New Yorkers (and billions worldwide) have kids, no car, and get along just fine. Subway trains are quite capable of carrying virtually anything you can carry. And bicycle trailers are pretty impressive specimens. And when you need to haul anything truly massive, sure, rent a Uhaul. But to pretend you need a 2-ton vehicle because you've got a couple little kids and a load of groceries for the week... c'mon.

It could work for a kid or two, but that family size isn't enough to prevent extinction. Somebody needs to have more kids.

For me, a load of groceries fills 3 shopping carts in the store (packed to the top and overflowing) and 4 once bagged. That seems to be about 42 cubic feet (1.2 cubic meters) of food, with weight likely approaching a ton. I still have to buy a bit more during the week, since we go through about 2 gallons of milk per day and I'm just not going to attempt bringing home and storing 14 gallons of milk.

I use a 3-ton vehicle by curb weight. It can be a 5-ton vehicle when filled. The 5.4L V8 gets 11 MPG in the city. It's actually fuel-efficient on a per-person basis when I fill most of the 15 seats with people; think of it as 3 times a 5-seat vehicle that does 33 MPG.

There is no way you can fit a week's groceries for a family of four in a bicycle trailer.

Most people fit their week's worth of groceries in a grocery cart, and manage to push that around the store. I really don't understand why it's crazy to think you could tow them home with a bicycle. Plenty of people do this. It's a bit out of the norm in the U.S., yes. But don't for a second think it's impossible, or even particularly challenging.
