Does "BRT double lane" refer to one 3.5m lane out of two, both together transporting 86k/hour due to leapfrogging efficiencies, or to both lanes together at 7m total? I think it's important to maintain consistency with the 3.5m theme!

I would guess the former, as a single bus line usually doesn't run a constant stream of buses nor express routes, but leapfrogging could allow you to run multiple bus lines along the same corridor, allowing for kinda ludicrous capacities.
Based on this data, the minimum headway and maximum current vehicle capacities, the theoretical maximum throughput measured in passengers per hour per direction (PPHPD) for a single traffic lane is some 150,000 passengers per hour (250 passengers per vehicle, one vehicle every 6 seconds). In real world conditions BRT Rio (de Janeiro, BRS Presidente Vargas) with 65.000 PPHPD holds the record, TransMilenio Bogotá and Metrobus Istanbul perform 49,000 – 45,000 PPHPD, most other busy systems operating in the 15,000 to 25,000 range.
Oh wow, I could believe that now! Tried looking up pics of Rio and Bogotá BRT to see if they are two-lane or one-lane. Some pics look as if it's 2-lane:
But it seems that's only around stations, the lanes merge into 1 later:
Wow, thanks for digging up some numbers on it. Those systems sure can move a lot of people. I certainly wouldn't mind having buses show up every 6 seconds.
People don't drive cars because they think they're efficient in absolute numbers. They drive cars, because cars are way more comfortable and faster than anything else in everyday life.
The only thing I wish is that we had more accessible and safe single-seat vehicles. I bring 3 empty seats with me to work every day. I would be more than happy to have a cheap, efficient single seat vehicle for commuting if it was safe. I'm not going to ride a motorcycle 25 miles each way every day in the Florida heat and rain. I'm certainly not going to share the road with the maniacs we have here on a motorcycle.

In other words, it isn't that biking or motorcycling or walking or whatever isn't safe, it's that the presence of cars makes everything unsafe (including the cars themselves).
Similarly, bike lanes etc. are car infrastructure, not bike infrastructure, because in the absence of cars cyclists would have no problems using the normal lanes. (Remember that the next time some dipshit complains about spending on bike lanes or cyclists not paying their "fair share.")
Pretty much every argument drivers have against other transportation modes is rooted in projection.
Smart Cars and the like are closer to this, but roads and parking spaces aren’t really designed to take advantage of their comparatively smaller size (eg you can’t drive them side by side down the road).
To be fair, Europe is sort of like this given how small their roads are
Yeah I wish we had a lot more public transit in the USA but a lot of these arguments do not compare convenience in any way. Most of those rail options are in no way more convenient. Especially for long distance. I took a train long distance once; or was almost as bad as flying in terms of schedule. Being able to come and go on my schedule is one of the biggest bonuses of driving.
That said, fuck cars lol
Ain't nothing comfortable about being in an environment where one wrong move will end your life
Not to mention how every time you drive a km, you kill a statistical fraction of a person. How do people do that fucking calculus? How many micromorts are you willing to inflict on others just to get some OJ from the store? People DON'T do the fucking calculus, that's how. They just push it from their minds, like they have been conditioned to by the religion of the automobile ever since birth.

Gonna use some of that suburban rail to travel dooway-to-doorway. Oh wait. No, you can't. It is almost as if having options for different needs is important. Instead let's use overly simplistic explanations for a rather complicated problem.
Where is the plane?
Mods are an incredibly inefficient way to moderate people.
