As far as I'm aware, the only city in the western world that truly kept its pre-automobile streetcar network was Melbourne, Australia. A result is it today has the largest tram network of any city in the world.

It hurts my soul to imagine how basically every city in North America had similar networks, but they were almost completely annihilated, save for small fragments in a small handful of cities.

Why can't we expect rural areas to have some form of mass transit? Having at least a bus system that services a rural area absolutely should be the expectation.

Now I can only speak for the US, but most major cities have ring roads or some sort of bypass that would be perfect for a hub and spoke sort of setup alongside them. Maybe it's just the fact that the university I went to famously has a light rail system and the concept is just embedded in me, but I'd imagine the uptake of a park and ride approach with stations out in the burbs (certainly not all of them, but laid out so that you don't need to go more than a burb or two over to reach a station) would be high enough to be worth it. Putting in some shops at the stations like an airport foodcourt would help offset building costs and whatnot to a degree over time as well. Then you could tie the hubs into other major cities in the state and you've got yourself a compelling transit system, doubly so if those cities have subways.

When I switched to riding my bike to work the commute was almost identical. However, I was riding in traffic and after my second close call with a car door I called it quits.

If we had dedicated bike lanes where I live I would 100% still be riding to work.

They're showing capacity, i.e., a 3.5m sidewalk can move about 15k people per direction per hour. I'm guessing there's leeway for cars depending on intersection types/design, speed, etc., whereas there is much less variation in average speed for pedestrians.

This visualization is space efficiency.

Obviously cars have terrible energy efficiency. The most efficient vehicle is a bicycle, since exercise is good for you it's arguably negative energy usage.

As for time efficiency, you have to consider car dependent development as a package. Everything spreads out, so overall there may not be an improvement in time efficiency, especially when you factor in the longer travel time of people not in cars. You could even consider the time spent working to pay for the car, or the time lost from people killed by the car, and I doubt cars would come out particularly time efficient then.

And usage of space. And money, at least if you include all the externalities.

They're measuring how many people can pass through a fixed point in space in an hour, not how long it takes one person to get from point A to point B.

So not really time or energy, but quantity.

The context is that they're showing one metric among many and are hoping you'll draw the conclusion they want: that cars are an inefficient way to travel. It'd be interesting to see distance and time metrics added. For example, while pedestrian capacity is pretty large, the distance travelled for any specific time period is short, so people aren't walking somewhere 100 miles away.

Similarly, door-to-door travel time can vary a lot. Suburban commuter rail around here is fast, but you need to drive to the station (because suburbs are designed for cars), wait for a train, commute on the train, then find your way to your actual destination from the station you get off the train at, so that might include walking or public transit.

Obviously, any one of the options can make the most sense in a given situation, but the infographic isn't trying to show that.

There is always exceptions and in some areas, you have to have some cars. But removing most of the cars and replacing most of the 8 lanes of traffic with alternatives would be more than enough.

> But cars have their place.

True. However with all the downsides of cars, they should be only the fallback if most other options don't work. As it is, in many places, they are the highest priority that everything is planned around.
