Nearest grocery store is a little over 3 miles. Libraries about four and a half miles. Nearest passenger train is about 200 miles away. I think there's a bus stop about half a mile away but I don't know if it's a full-service one.

• To the nearest convenience store: 1.3km (small supermarket)
• To the nearest chain supermarket: 2.25km (Trader Joe's)
• To the bus stop: 321m (busses 30 minutes apart)
• To the nearest (public) park: 1.1km
• To the nearest big supermarket: 2.89km (Safeway)
• To the nearest library: 1.3km
• To the nearest train station: 1.8km

Straight-line distance to Golden Gate Bridge: 11.6km

It isn't just that things are too far to walk, it's that American car companies have made it part of our culture to own and drive, and it's unpatriotic to do otherwise. That causes a severe lack of public transportation and sidewalks and bike lanes. So because of all this, I have to drive a mile through my neighborhood to get to a 7-Eleven that would be a quarter mile if I walked.

Based on the small town where I grew up:

• convenience store: 2km
• nearest chain/big supermarket: 5km
• bus stop: what bus?
• park: 10km (but there are hiking trails within 1km)
• train (metro) station: 5km
• library: 5km
• long distance train station: 20km
• my dad’s daily commute when I was growing up: 140km (that’s 140km each way, 5 days a week. 1200km of commuting each week. He did this with a combination of car, bike, and train. It took him about 3 hours each way.)

Note that a lot of the roads don’t have sidewalks so even if you want to walk it can be kinda dangerous depending on time of day.

Based on cities I’ve lived in:

• convenience store: 300m
• chain supermarket: 800m
• bus stop: 500m
• train (metro) station: 1km
• park: 1.5km
• library: 1.5km
• big supermarket: 2.5km
• long-distance train station: 2.7km
• my current commute: 3km

The cities tend to be a lot more walkable, but you still need to take the car or train to get to things like by the bigger (and cheaper) supermarket and other stores. The train is slow and unreliable (sometimes it’s faster to walk than take the train) so cars are much more popular.

I live in New York (city):

• Convince store: several within 1-2 blocks
• Grocery store: 1 block away
• Train station: 3 blocks away
• Park: less than a block
• Library: Very short train ride (4 stops) and a bit of walking (15 minutes) (there is a closer one but that requires a bus and considering New York traffic busses aren't the best).
• Statue of Liberty: Roughly 2 hours by train

I used Google maps to get these values. I'm using Google's estimated walking distance and will also include Google's estimated walking time.

I'm in Utah somewhere south of Salt Lake City (the state capitol). The numbers aren't great, but they're far better than some places I've lived here. As a kid, I remember biking for 20+ minutes to make it to a small supermarket.

EDIT: as others have said, my paths can be quite bendy at times, but it's different than many suburbs in the US. Salt Lake City (and, by extension, most of the valley that it's in) is built on a fairly rigorous grid system. We have lots of straight roads with large blocks (in some cases, it can be 1-2 km between lights and crosswalks). We don't have too many ratfucked suburban mazes, so the walkability problem here is primarily due to sprawl and a dearth of crosswalks.

Distances seem about the same in my small US town.
No train.
Little further to Big Ben, i think.

I live in a walkable neighborhood in Richmond, Virginia. I have grocery stores in walking distance but usually drive to nicer ones for big hauls. I drive to the gym. I could bike there but there’s no bike lanes and steep hills. Everything else on your list is just a few blocks away.

Living in a small town in central North Carolina (answering these questions in units of city blocks that are ~150 meters long or in statute miles:

To the nearest convenience store: 4 blocks

To the nearest chain supermarket: 2 miles

To the bus stop: ~35 miles (It's a distance to the nearest town with a bus service)

To the nearest park: 8 or 9 blocks

To the nearest BIG supermarket: 2.5 miles. The "nearest chain supermarket" is a Food Lion; slightly farther down the road is a Wal-Mart and a Harris Teeter about the same distance away.

To the nearest library: 3 blocks

To the nearest train station: 4 blocks.

Straight-line distance to Big Ben: ~4000 miles. juuuust out of earshot. I don't recommend walking.

Just to give the other side. I live in a big city in the US.

• Convenience store: .2 miles, 320 meters

• Chain supermarket: .5 miles, 800 meters

• Bus stop: 300 feet, 90 meters

• Park: 0.2 miles, 320 meters

• Big supermarket: 0.4 miles, 640 meters

• Library: 0.9 miles, 1.4 kilometers

• Train Station: 0.3 miles, 480 meters

I live in rural Ohio and I drive about 40 miles (65 km) round trip a day just getting to and from work, and that's pretty average for a rural area.

The nearest grocery store and back is about a 15 mile (25 km) round trip.

In the rural areas, which account for most of the land area of the US, things are far enough apart that it makes it impossible to survive without a vehicle.

Far.

It is fucked here unless you own property already in the good parts or you are upper class income and can move your ass into the good parts despite the obsene costs.

Let's give it a shot. I live in the suburbs of Lincoln, Nebraska, which is an average-sized college town in the US (about 300k residents):

• Nearest convenience store: 1.1 miles/1.7km (we often do walk there, takes about 20 minutes)
• Nearest chain supermarket/big supermarket (they are often one in the same here): Target @ 1.5 miles/2.4km
• Bus stop: 1.3 miles/2.1km
• Nearest park: 0.6 miles/965m
• Nearest public library: 3.5 miles/5.6km
• Nearest train station: 9.1 miles/14.6km (we don't really use trains much at all in the US, though)

Here are my walking distances in Seattle:

It depends what region your in.

City: depends where you live, i.e. how close to "downtown" you are. A lot of stuff is walking distance, but not everything. You could walk to school and get some basic food or a pharmacy. Probably need a car/bus for work or larger grocery trips.

Suberbs/town, you might be able to walk to convince store or to school/library, everything else is going to be a car or about a 30min walk. That being said, sometimes you're "deep" in the suberb and the nearest convince store is a 20-40 min walk.

Rual/farm: you need a a car to visit your neighbors. Nearest grocrey is a 30 min drive away.

Depends.

If you live in a very rural area it can be more than an hour by car to some of these things, 50 miles or more, other items may not exist at all like public transportation. Inter-city public transportation is all but imposable for smaller locations, difficult and lengthy the greater the distance and size differential in locations.

I used to live in a metro area. Everything was within 10 minutes walk except medical care, but walking to the subway would get you to top tier medical facilities in about 15-20 minutes. Getting to nearby “bedroom” communities was also pretty easy thanks to a commuter rail.

I now live in a suburban area that has OK bus service but it’s not very convenient to where I live at all. Everything is within a 10 minute drive, and unfortunately a car is necessary due to the lack of sidewalks in many places. It does have light rail to a major metro area, about two hour’s ride, and then you can access the metro area major transportation network to all nearby areas and further away. Probably about as good as it gets in the US.

Nearest store of any kind - 1 mile

Full serve store - same

Library - .75 mile

Bus stop - 1.2 miles

Small park - .5 miles

Large park - 3 miles

Access to light rail - 4 miles

Take a look at a population density map of the US. A lot of the places that don't light up are agricultural. If for some reason you have never seen a real farm before and always wanted to then by all means come on by, but we call them "flyover states" for a reason. All the cool tourist destinations are in the glowy bits.

I assume you were asking for tourist reasons anyway. If you were just asking for curiosity sake, it depends where you live. I live in the rural part of Illinois and it only takes 15 - 20 minutes to get to a supermarket by car, but walking there is completely out of the question. Especially with the hills. Oh God, my feet hurt just thinking about it.

I went to College about 65 miles west of Chicago (or about 1 hour driving). One weekend some friends decided to take a road trip to Maine so one friend could confess their love to someone. They left Friday after classes ended and drove nonstop, took one hour in Maine for the friend to get shot down, and then dove back. They didn't get back until late Sunday night. That's about 1300 miles and with a few bathroom/food stops 24 hours each way.

At my parents' place, it's about 9 miles (~14km) to the nearest gas station/convenience store, which has super limited hours, or roughly a 15 minute drive. It's about 14 miles (~23km) to the nearest grocery store, or about a 20 minute drive.

I live in the suburbs of a major city, so the nearest stores from me are around a mile (1.6km) away. The nearest big supermarket is like 2 miles (3.2km) away.

Things around me aren't that far per se, but you have to cross a 45mph road (where people regularly drive 55-60 because it's designed like a highway) along several sections of unconnected sidewalk if you want to get there without a car. The sidewalks are 4ft wide at most and have no separation from the car lanes so you have to walk with cars whizzing by just a couple feet from you. There's also no shade.

For reference - it takes 5 minutes to drive to the nearest grocery store 1 mile away, but walking it's 31 minutes with the unpleasant conditions I mentioned. So I've never walked there. I could bike and it would take 10 minutes, but biking along cars at 50mph doesn't sound fun. I also live on a bike path, but it doesn't go to the nearest grocery store so the nearest one along the bike path would take the same amount of time as if I walked to the nearest one (25 minutes). That one is 3.5 miles (11min) by car or a 1hr walk.

Depends on the state. There are places where stores are 2+ hours away by car.

In my area, it falls into 2 categories-

1. Things are 20-30 min by car and are 20-30 miles away (highway)
2. Things are 20-30 min by car and are 3-5 miles away.

This is totally based on traffic and roads- I’m in the woods outside Washington DC, so while the density is high in the cities, I’m 15 min from literally everything minimum (by car). I couldn’t walk or bike to a store, I’m 30ish min from work combination highway and local roads.

If you live in a city, you might live literally on top of stores in the same building. Shopping centers with above condos and apartments are becoming a popular replacement for shopping malls in my area, but are very very expensive (often over $1million) for a townhouse in one of these shopping “communities”.

I buy nearly everything online and have it delivered, most stuff (groceries, goods, electronics, housewares, etc) come between 0-3 days.

Nearest convenience store is 200m Chain supermarket is 200m Bus stop is 150m Library is 50m Park is 500m Train station is 800m

NYC makes everything easy

Depends heavily where you live. Rural places can be an hour drive to the closest grocery store. For me, I live about 5 minute drive from stores and my work. But I cannot feasibly walk to where I want to go, there is zero sidewalks in my area and cars go at least 35 mph on the slow neighborhood roads and 50 mph on the busier main roads (less than 3 minute drive to get to either one). Bus and train infrastructure is basically non-existent so not an option. My only option is risk my life on a bike on the shoulder of the main road (since theres no bike lanes) and hope the weather isn't bad or I have to drive a car .

I live out west. Think of how far would be intolerable to walk in 45 degree heat and then add 30 minutes standing by the road, waiting for traffic lights to change, so you can attempt to cross without a crosswalk or a sidewalk, while you roast in the added heat from car exhaust.

It varies wildly depending on where you go. I think the worst-case scenario in terms of car-built cities would be someplace like Phoenix, Arizona. Visiting that city, I gained an appreciation for what it must be like to have a physical handicap that affects your mobility, because being in Phoenix without a car is comparable to having a disability. You cannot go anywhere on your own two feet in any reasonable length of time. It's the kind of place where you need to find a Walmart to buy a loaf of bread. The closest thing to a corner store is going to be a gas station.

My refrigerator is annoyingly far from my desk chair.
