      What nonsense?

      50k PPHPD is near the top of what can be easily achieved in a metro with one track per direction, but certainly achievable. 2x4m wide tracks and some space for ancillary equipment and fencing is reasonable.

      You get maybe one passenger per two seconds in a car lane, or about 1800 per lane per hour. That implies 28 lanes each way, 55 total, or about 165m assuming 3m lanes (pretty narrow). Seems fair to me.

      No comment on buses, cyclists, or pedestrians.

        Roads with 56 lanes are not a thing and I don’t see the need for implying they were. In reality you would probably get way less route capacity as transport just doesn’t scale linearly like that. There is a perfectly fine graphic on Wikipedia that gets the same message across without implying anything absurd.

          Isn’t them not being a thing kinda part of the point. You see how stupid the building must get to reach the same throughput

          roads with 56 lanes are not a thing.

          Maybe not yet. Keep following the “just one more lane, bro” planning strategy and we will have them by 2050.

          Are you the kind of person who thinks “Where’s the any key?” when the computer says “press any key to continue”? Like, overly literal, inability to parse intent and deep meaning?

          Partly this is because there are 2-4 roads in parallel attempting to move the same number of people, or demand is unmet because people can’t get to where they want to go when they want to go.
