From a Midwestern standpoint, that is madness.
I work a lot of odd hours. Carpooling is not possible, as that means I either adjust my schedule or they work mine. Also, in most areas here public transit is not possible. It doesn’t go where I need or want to.
However, we don’t have the congestion. Land is cheap enough you can build lots. Businesses are located in the rings around the cities, not in the core (or they have moved). Unfortunately, I see many “city planners” wander in and demand that we start building like you propose. They built one development like that, and not only did the houses not sell, the contractor sued the city. Biking 20 miles during an Iowa winter (or summer) isn’t going to work well. Most employers will not put up with the delays that come from it.
The key is to plan according to what the area requires. What we do will not work in NoVa (my wife’s cousin lives in Loudon county). What you do will not work here (unless you move a lot of manufacturing downtown). Work with what you have.
A vast majority of the HOV/HOT commuters are government employees. They are given the ability to to use the van pools, buses, or car pooling.
After I retired from the military and became a contractor my office was directly in the DoD buildings due to my work being mostly classified. I would arrive at the office at 0530 and open it up then around 0700 the government employees and military would start wandering in. Most of them were car pooling, van pooling, or such. In the afternoon, while myself and the other contractors were still working, they would all pack up to go catch their rides home leaving me with mostly contractors to finish up whatever had to be done. Even when I worked at the same Agency as a military type I never was able to use a car pool or such. I don't know how they got to do it but I was always doing most of the work.
The thing that chapped my butt was how I would hear all these Govies talk about how all the contractors were overpaid and lazy and they did all the work when they never spent a full eight hours in the office due to their car pooling and then only their names were placed on the work the contractors performed.
Returning to the car pooling business: most civilian contractors do not have the luxury of finding a way to use the HOV/HOT lanes due their contract requirements, although I did have one contract that allowed me to stop at the Pentagon parking lot and pick up Slugs, but that contract only lasted three years.
I rode a bike to work for years. My commute was under two miles. This is typical; the average bike commute is under seven miles, and a lot are much shorter than that.
The long distance spandex warriors are numerically insignificant. From a planning standpoint, they are an indicator species. Their presence means that they have a viable migration corridor, i.e. enough decent biking infrastructure that they can actually find a practicable route. Around here, most of this would probably consist of quiet, bike friendly streets in residential neighborhoods, supplemented by a few of the trails that go somewhere useful (as opposed to pleasant recreational rides along the streams and in the parks). When you see the long distance guys on a crowded road where they clearly don't belong, it's usually because there's a gap in the good bike route, and they're flushed onto busy streets until they can dive back into cover.
IOW, when you see the spandex warriors on commuter roads, don't rail at the stupidity of the riders. Consider instead what their presence is telling you. Look at a bike map and see where the gaps are. A lot of the action in DC bike circles focuses on bridging the gaps so you can move easily from neighborhood to neighborhood without killing yourself trying to get across an arterial road.
Don't think of bike commuters as long distance performance artists. Most of them are just moving around their own neighborhoods. A very high percentage of trips by car are under five miles as well. That's an opportunity to reduce congestion, if we can get a reasonable percentage into walking or biking. With good design, biking infrastructure becomes a neighborhood amenity that attracts active young people.
