2. Roads existed before cars. This is an extremely American view to think that roads should be exclusively for cars. Roads should be for PEOPLE, regardless of which mode of transport they are using.
Okay, but now cars do exist. Do you think it's reasonable for cars capable of traveling 40mph should be stuck behind pedestrians at walking speed? Our modern transportation infrastructure exists for a reason, and that reason is speed/effeciency. Most areas with heavy pedestrian traffic have sidewalks. If I'm going 60mph down the highway then the presumption that I should be subjected to pedestrians casually strolling across is absurd.
If you try to compromise, you end up with stroads... which turn out to be just as bad as highways for pedestrians in practice, thanks in no small part to people like you who believe that all of the compromises of street design and urban planning should be borne not by vehicular drivers but by pedestrians.
(I'll add a side note here: a lot of efficiency depends on what you're trying to make efficient. Many people--including you, apparently--define efficiency as moving cars with as high throughput as possible. If you instead want to move people with high throughput, usually step one is to ditch cars, since single-occupant vehicles occupy vastly more space than any other form of transportation.)
In the few places with high 100% walking commutes, I don't see cars being more efficient either. Do you want every college student to drive from their dorm to class? How about poor countries without the money to maintain good road networks?
This entire discussion started as whether pedestrians should/shouldn't be on roads. No, they shouldn't. They should be on a sidewalk, best of both worlds.
For 2, I'd make a distinction between paths built for long-distance travel (roads) and paths built for connecting to destinations (streets). The two have fundamentally different goals that cannot be safely achieved at the same time. To allow for high-speed travel, a road should be as predictable as possible, with limited entrances and exits and barriers to prevent people and animals from wandering onto the road, and should be restricted to vehicles that can maintain a high speed. To allow streets to connect to destinations; such as homes, shops, and workplaces; there should be many entrances and exits to the street. The destinations should be packed as tightly as possible, so that they can be reached with a minimal distance traveled. It's not just that these goals require tradeoffs, but that they are fundamentally antithetical to each other.
The best way to satisfy these two goals is by having separate designs for streets and roads. The roads are pathed around pedestrian areas, and allow branching off into them at limited locations. The streets are mixed use, with rougher surfaces (e.g. brick/cobblestone) to prevent high-speed travel. This doesn't exclude motor vehicles from using roads altogether, allowing for use cases such as delivering food to cornershops or dropping off somebody with limited mobility, but does steer motorized traffic off of the streets and onto the roads wherever possible.
As for the later, why is that any better than just sidewalks and crosswalks, which the majority of areas with heavy pedestrian traffic already have? It'd be incredibly eco-unfriendly, expensive, and impractical to have two different types of roads for cars and pedestrians when we already have a solution that works just fine - sidewalks.
* "Most areas with heavy pedestrian traffic have sidewalks." I am uncertain on this one, as heavy pedestrian traffic is more frequent on mixed-use streets. Sidewalks are only used in places with car-centric design, which discourages walking.
* "Even with cars taking up much more space, a bunch of cars traveling at 25 mph are able to carry a many more people through a distance X in a period of time T than the equivalent walking would be able to." I am uncertain on this, because cars require very large amounts of space both for the physical size of the car, the spacing between cars, and the spacing between groups of cars at an intersection.
* "It'd be incredibly eco-unfriendly, expensive, and impractical to have two different types of roads" I'd be interested in a source for this, as I've generally heard that separating out usage improves the efficiency of each. Cars go faster because there are fewer stops requires. Pedestrians die less often because there are fewer cars nearby.
* "Bike lanes are less common than sidewalks" This is correct by my experience, but I've only lived in places with car-centric city planning. Can you provide a source?
I'm interested in continuing this conversation, but not if it is a conversation between sourced comments and unsourced assertions.
2: Roads are also for bicyclists, motorcyclists, and even pedestrians. It's true though that car drivers often think that roads are a car only domain and behave aggressively towards the other mentioned groups
But I refuse the popular notion that roads (as in larger streets, or any street between villages/towns/cities) should be for cars only. The usual examples of Copenhagen, Amsterdam or recently Paris show that shared roads lead to a higher quality of living. I personally appreciate this, and I'd prefer a world where this sharing would be more common.
You've clearly never had a UPS driver scream "Use the bike lane!" at you after parking his truck in that same bike lane. Drivers have bizarre reflexes for how to use roads.
For example for my messanger on my horse so he doesn't get stuck in the mutt on it's voyage to the next city. ... or maybe my zenturie to support my legion?
What makes you think (or suggest) that roads where invented for cars?
